K1: Keynote + Opening. 360° Immersive technology, how will you be transported right there, in person, instantaneously. Patrice Roulet (immervision.com)
The consumer devices of tomorrow are evolving beyond capturing classic pictures and videos. The lenses of yesterday are narrow and restrictive. New generation of super wide angle lenses capture our surroundings in full 360°, allowing our friends and families to step inside our universe and experience it, live.
Qualified as a most social platform by some and a game changer by others, this new generation of 360°/VR devices will impact the way people express themselves, share moments, and enjoyed unlimited unique experiences.
As example, we have seen off the shelf smartphones easily turning to virtual reality headsets. Next gen smartphones will become a gateway to your full immersive environment, enabling from the same device: 360° Virtual Reality capture, instantaneous sharing and immersive live experiences allowing us to share our world, our live, our feelings and our emotions.
This is the tip of the iceberg. Social media and app developers are yet to unlock the full potential of immersive 360° technologies. Its potential is only limited by our imagination. Starting from professional TV broadcast and movie cameras scaling up to our day to day consumer devices such as smartphones, this talk will explore a near future where we will never miss the unique feeling to be there.

- 10:30 Improving Performance of Dual-Polarized MIMO Ultra-Multilevel OFDM Under Mobile Reception
- The reception characteristics are improved by proposed MIMO-ICI canceller using iterative detection for dual-polarized MIMO ultra-multilevel OFDM under mobile reception.
- 10:50 Pattern Gain Based Compact 4-port Antenna for WLAN System
- For VR/AR service, it is necessary to obtain high throughput in wireless local access network (WLAN). Conventional multi-port antenna is not appropriate for WLAN devices due to space constraints of the WLAN device. Meanwhile, it is possible to obtain multiplexing gain by achieving pattern gain. However, previous antennas with pattern gain have not been designed for the WLAN devices. In this paper, we designed a compact 4-port antenna for the WLAN device, which is 0.5 times smaller than the conventional antenna. We also show that the proposed antenna obtains close multiplexing gain compared to ideal antenna in poor channel cases.
- 11:10 Performance Evaluation of Satellite Broadcasting Using SC-OFDM for 4K/8K Transmission

As the results, it is possible to increase the transmission rate against the required Carrier to Noise Ratio.
- 11:30 Modified Nonrecursive Comb Decimation Structure
- TThis paper presents the nonrecursive comb decimation structure for the decimation factors which are the power of five. As a difference to CIC (Cascade-Integrator-Comb) structure which is area efficient, a nonrecursive structure is a power efficient. However, this structure has a low attenuation in the folding bands (bands around the zeros of comb filter), which can deteriorate the decimated signal. We proposed a modified structure in which a simple multiplierless filter is inserted in the last stage. The proposed method is based on exploiting the properties of the system function of the convolution of a comb filter with itself.
- 11:50 Massive MIMO for Dynamic Spectrum Access
- This paper proposes the application of massive MIMO, combined with millimeter (mm)-wave technology, in dynamic spectrum access (DSA) systems. In the proposed system, secondary users transmit together with the primary users, while using beamforming to control interference. Simulation results show significant performance gains compared to traditional DSA due to increase of antenna numbers. Such system can be used under both line of sight (LOS) and scattering channel conditions.

In order to achieve these goals, we analyze the existing solutions and design and propose a new method of user interaction for a first person shooting (FPS) game prototype. In our FPS prototype, wearing a head mounted display together with two motion controllers, we design the player interaction using both hands to operate in-game firearms and mimicking shooting action in real-world. Additionally, we make use of one of the trending and free game engines in order develop a run-able game prototype.

However, the success of immersive video is impeded by the limited effective display resolution of 360 degree footage. In this paper we present a general methodology to assess resolution loss during the projection process and therefore help to design novel 360 video systems.
- 10:30 Fast Semantic Region Analysis for Surveillance & Video Databases
- The importance of real-time surveillance video monitoring has increased recently in response to heightened security concerns. For real-time implementations, it is important to develop surveillance systems with low computational complexity. Here, we analyze the complexity of our semantic region labeling approach which aims to extract spatial contextual information in a video. In our approach, besides color and texture, also the vertical position is taken into account as part of a gravity-based model. We demonstrate that our system provides low computational complexity while maintaining a high accuracy which makes the system suitable for real-time implementation in embedded video surveillance.
- 10:50 JPEG 2000 Compression of Unfocused Light Field Images Based on Lenslet Array Slicing
- This paper proposes an algorithm for lossy compression of unfocused light field images. The raw light field is preprocessed by demosaicing, devignetting and slicing of the raw lenset array image. The slices are then rearranged in tiles and compressed by the standard JPEG 2000 encoder. The experimental analysis compares the performance of the proposed method against the direct compression with JPEG 2000, and JPEG XR, in terms of BD-PSNR gain and bit rate reduction. Obtained results show that the proposed method outperforms direct application of the reference state of the art image encoders.
- 11:10 Building Recognition with Adaptive Interest Point Selection
- In this paper, we propose an improvement of image retrieval for building images using the Bag of Words (BoW) model. The principles consists of pre-processing the interest points detected on the images in order to classify them into two classes, corresponding to building and no-building key points. In this way, the data involved for comparisons is reduced to only the relevant one and only the features describing the buildings are taken into account. The experimental results, carried out on the Paris6k data set shows significant improvement in terms of retrieval performances.
- 11:30 A Novel Intelligent Video Surveillance System Based on Embedded Devices
- Intelligent video surveillance has attracted extensive interest due to the great market demand. In this paper, we present an intelligent video surveillance system, which uses an hardware-oriented foreground detection algorithm based on Mixture of Gaussian model. The surveillance system with an intelligent board can realize 7 different monitoring tasks in real time, such as intrusion detection. In order to improve the detection accuracy, we use an object size detection threshold to eliminate the interference of some irrelevant moving objects in dynamic scene. The experiment results prove that our system has good performance of tolerating the interference of shadows, ripples, etc.

Sunday, January 8, 12:25 - 13:30
A recent VR First survey with the participation of academic institutions around the world shows the high interest of academia in teaching VR development but the lack of infrastructure to realize their goal. Universities cannot provide students with VR development hardware to apply theoretical skills, nor do they have prepared a curriculum to teach practical VR development skills. VR First is facilitating an industry cooperation to support universities in their goal of VR education by providing facilities, equipment, skills, mentorship and a network to empower innovation and realize the existing spin off potential.
VR First believes that every developer should have the opportunity to access to high-end VR infrastructure to develop the most immersive VR applications of the future.
In this session, it's going to be discussed how to empower students and developers with the skills and network to succeed in the VR industry.

- 13:50 Software Framework for Runtime Application Monitoring of Fail-Safe Multi-Processor ADAS SoCs
- In Advanced Driver Assistance (ADAS) systems, it is very critical to ensure a system malfunction does not cause harm to humans (also referred to as functional safety). Malfunctions could be due to incorrect software (SW) execution. Many techniques exist to catch systematic SW faults during development. However without run-time monitoring, it is impossible to guarantee a fail-safe system. In this paper, we describe a framework to monitor application statistics in heterogeneous multiprocessor SoCs targeted for fail-safe ADAS systems. With <0.5% CPU load overhead per monitor, the proposed framework was found to accurately report statistics for a front camera analytics application.

This template was used to calculate correlation between observed signals. The proposed method amplifies a weak heartbeat signal and reduces road noise. A basic experiment was conducted on an actual road at low speed. The proposed method detected the heart rate with accuracy exceeding 85% relative to heart rates measured with a contact-based system.

The triaxial accelerometer module detects the tilt angle of the tray. The MCU expansion board controls the four servo motors which are utilized to balance the tray. The four FSRs in the tray will sense the carried item positions and the four LEDs will show the weight position.

- 14:10 Touched Image Transmission of a High Resolution Touch Panel Using MIPI CSI-2 for Kiosk Applications
- This paper presents high-speed image data transmission using MIPI CSI-2 interface for high-resolution touch panels. On MIPI CSI-2, if there are errors, the receiver notices these errors to upper-layer including application layer. Error-handling is a duty of application layers. In this case, touch response increases consequently. In this work, we added error handling path to low-level protocol layer. In addition, to compensate for signal attenuation due to increasing transmission distance, the adaptive equalizer using FVC(frequency-voltage converter) was applied to the receiver. The proposed architecture was tuned with 800Mbps that transfers data of 800x600 high resolution panel less than 10ms.

This product, consisting of sensor module, controller module and transmission module, is embedded in tennis handle. There are three steps for stroke recognition. Firstly, shot detection uses fluctuation of acceleration based on moving windows. Secondly, sensor data are used to divide those shots into 3 stroke types (forehand, backhand, serve). At last, information about how the ball rotates would be acquired. The experimental result shows high accuracy for motion recognition with 98% accuracy for shot detection and 96% accuracy for stroke recognition.

A general consumer of the service can easily verify the issued digital certificate in an online manner. The presented framework aims at diminishing the chances of modifying digital contents of the holy book for its consumer's belief and trust.
- 13:30 Towards an Optimized Multiview Streaming System with View Interpolation
- We present an approach to optimize the transmission of multiview video over bandwidth limited channels. The main idea is to optimize the number of transmitted views by choosing a set of views to be reconstructed at the receiver using view interpolation, removing them from the stream and encoding the remaining views with a higher quality. We have shown that this approach makes sense especially in cases where the channel is very restricted. With further evolution of view interpolation algorithms, the threshold at which our method improves image quality rises quickly and can be applied to a wider range of scenarios.

- Performing image retrieval in large image database is becoming popular. ISO/IEC moving pictures experts group (MPEG) drafts compact descriptors for visual search (CDVS) to support the related applications. In this paper, we adopt CDVS to address traffic vehicle search in large database. After detailedly analyzing to the local descriptor, we firstly define local descriptor distinctive degree based on the gradient quantity and the spatial gradient distribution energy of the feature. Then we propose our adaptive feature selection method by combing feature distinctive degree and priori information. The proposed method is proven to be better than the standard algorithm in CDVS.

Next, the variational-based minimization is iteratively performed to estimate reflectance and illumination simultaneously. Finally, the color assignment method is performed to the estimated reflectance component to restore the color component using the input RGB color channels. Experimental results show that the proposed method can provide better enhanced result without saturation, noise amplification and color distortion.

K2: Keynote. Electrostatic Discharge (ESD) Protection of Low-Voltage Consumer Electronics: Challenges and Solutions. Juin J. Liou (University Central Florida)
There has been a wide spread use of integrated circuits in consumer applications. For example, due to the huge market of civil wireless communications, low-voltage integrated circuits are in high demands. To ensure the reliable daily use of these electronics, development and implementation of robust and effective ESD structures which operate within a very narrow ESD design window and with a minimal loading effect (i.e., high transparency) are required. Unfortunately, a set of constraints and challenges must be overcome before such ESD protection solutions can be realized.
A brief overview on the ESD protection guidelines, schemes and testing will first be given in this talk. This is followed by presenting various ESD designs aimed for meeting the stringent ESD requirements imposed by the modern CMOS and emerging FinFET technologies. Challenges and solutions pertinent to this objective will be emphasized and addressed.

- This paper presents the design scheme of a passive intermodulation distortion (PIMD) finder in order to find out the birthplace of PIMD which is introduced by sharing a feeder cable in in-building wireless multi-band networks. To this end, a frequency-modulated continuous-wave (FMCW) signal generation module and a fast Fourier transform (FFT)-based signal processing module are implemented to figure out the exact PIMD occurrence point. By improving the common feeder cable conditions with the timely PIMD detection, mobile consumer devices are expected to be well operated in in-building without call drop due to the PIMD.
- SDN-based Distributed Mobility Management for 5G
- Distributed mobility management (DMM) is an attractive approach to address the mobile traffic explosion problem, and thus it is perceived as a promising technology for mobility management in 5G. In this paper, we propose a software-defined networking (SDN) approach for DMM (denoted by SDN-DMM). Unlike the existing approaches for DMM (i.e., network-based or terminal-based), SDN-DMM implements the location and handover management functions at the centralized SDN controller while the packet forwarding function is fully distributed at access routers. Therefore, SDN-DMM can achieve the packet forwarding path optimization and provide significant benefits in terms of network and traffic management.
- The Design of Non-AS Signaling for Multi-Rats Traffic Steering
- Different types of 5G services scenarios impact on 5G network architecture to support multi-RATs such as 5G Rats, WiFi, and fixed network optimized for requirements of different services. Therefore, new signaling architecture between Consumer Electronics (CE) and Core Network (CN) in a 5G system needs to be designed for optimizing the coordination among different access networks. We propose the design of non-AS signaling architecture between CE and CN through multiple access networks to support various types of services in 5G and beyond.

In the proposed scheme, an access point (AP) with multiple antennas finds the optimal number of the antennas for transmitting and receiving signals to maximize the sum capacity of the uplink and downlink transmissions. We carry out a simulation and show that the proposed scheme can improve the sum capacity in the full-duplex wireless networks.
- Delay Oriented VR Mode WLAN for Efficient Wireless Multi-User Virtual Reality Device
- In order to enhance user experience of Virtual Reality (VR) devices, multi user VR environments and wireless connection need to be considered for next generation VR devices. Wireless local area network (WLAN) is a popular wireless consumer device which can provide high throughput and can be installed with low cost using unlicensed band. However, WLAN may cause delay in packet transmission due to its distributed nature in channel access. In this paper, feasibility of wireless VR over WLAN is carefully examined and an efficient multi user VR communication scheme using the next generation WLAN is proposed for multi-user VR services.

- Scheduling Optimization for M2M Communications in LTE-M
- One of the major challenges for Machine-to-Machine (M2M) paradigm is the capability to scale to a larger number of connected devices and to provide ultra-low delay communications in order to meet future Internet of Things (IoT) requirements. In this paper, we study the performance of LTE-M protocol in terms of delay, throughput and bandwidth utilization. Next, we propose a novel scheduling mechanism for LTE-M to support M2M communications. The ultimate goal is to optimally allocate the resource blocks to different users in efficient manner in order to maximize the usage of the available bandwidth and reduce communications delay.
- Performance and Security Oriented Software-Defined Network Interface Design
- Owing to the growing trends in network bandwidth, the network packets of such applications may need complex processing. The standard network interface does not perform any advanced processing for the packets of these applications. Although hardware acceleration module can improve the performance, it lacks the flexibility. This work proposed a Software-Defined Network Interface (SDNI) to define the hardware behavior by software. Four action modules in the SDNI are provided to support the processing of network packets. The experimental results show that this work can ensure the security of data transmissions, and can reduce by the time consumption of encryption 45.19%.
- A Comparison of ESPAR-MIMO and LMA-MIMO for Single-RF Transmission of Spatially Multiplexed QAM Signals

In this paper, we compare our LMA-MIMO with ESPAR-MIMO in terms of the dissipated power, circuit stability, and bit error rate performance. Owing to both pure reactance and phase control loading as well as self-matched impedance loading, we show that the LMA-MIMO outperforms the ESPAR-MIMO by reduction of 52~81% in power consumption and 5.8~41.6% in BER without any problems of the circuit oscillation.

K3: Keynote. The Emerging Era of Fog Computing and Its Impact on Consumer Electronics. Tao Zhang. IEEE Fellow and Cisco Distinguished Engineer.
Moving computing, control, and storage into the Cloud has been a key trend in the past decade. However, Cloud alone is encountering growing limitations in supporting many new systems and applications such as the Internet of Things (IoT), 5G wireless systems, distributed data analytics, embedded AI, and more. Addressing the growing need for distributed computing requires a new paradigm - Fog, which can dynamically distribute computing, storage, communication, and control services closer to the users, to the network edge or anywhere along the Cloud-to-Thing continuum that can best meet user requirements.
Many new challenges arise in enabling Fog computing and services, creating a fertile ground for innovation. What Fog architectures make the most sense? How should Fog interact with Cloud? How to enable scalable, manageable, and reliable distributed Fog systems and services? How to secure such Fog systems and services? The list continues. Addressing these challenges necessitates rethinking of the end-to-end computing, networking, and control architectures.
In this talk, I will discuss what Fog is, how it complements and differs from other related technologies and initiatives, how it can help address some critical challenges we face, and what the global industry-academia consortium - Open Fog Consortium (OpenFog) - is doing to accelerate Fog development and adoption.

- 16:30 Mitigating Row Hammer Attacks Based on Dummy Cells in DRAM
- This paper presents an alternative to prevent data corruption in DRAM memories due to Row Hammer attacks by the usage of dummy cells connected to each row as attacks indicators. These special cells are characterized for having a higher sensitivity to coupling noise. The strategy was validated by simulations on a 65nm CMOS 64x64 memory array, including process variations for coupling and interconnections. A outstanding characteristic of this suggested solution is the low-complexity additional hardware.

- 16:10 Speaker System with 100-W High Output Power and 0.17% THD Using 9-V Power Supply with Digitally Direct-Driven Technique
- In recent years, high-quality and high-efficiency speaker systems have grown in importance. However, to improve sound quality, implemented electric circuits increase in size and consume more power. In addition, efficiency at low output power and total harmonic distortion (THD) at high output are degraded. In this paper, we report on a small speaker system that can output 110 W and higher from an 9-V input without using analog circuits. Using only digital processing, we build a low-power, fully digital speaker using a digital direct-driven speaker system (DDDSP) that can achieve high efficiency, low noise, and low THD.
- 16:30 A Tablet Personal Computer with Diagonal Microphone Placement for the Landscape/Portrait Interchangeable Mode
- This paper proposes a tablet PC with diagonal microphone placement for landscape/portrait interchangeable mode. Two microphones are diagonally located at a screen corner to provide useful directivity for interference attenuation in both landscape and portrait modes. The diagonal microphone placement guarantees a nonzero microphone spacing in either the landscape and the portrait mode so that interference attenuation is achieved for good subjective signal quality and a higher speech recognition rate. Evaluations in speech recognition scenario demonstrate that the diagonal microphone placement is effective in both the landscape and the portrait position with comparable command recognition rates of about 90\%.
