From RFID to Cyber-Physical Systems: Reality, Dreams, and Fantasy

Prof. Magdy A. Bayoumi, University of Louisiana at Lafayette

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

“Sponsored by the IEEE Council on RFID under its Distinguished Lecturer Program”

Date : 25 July 2019 (Thursday)
Time : 10.00 AM - 11.00 AM
Venue : Meeting Room B1 (S1-B1b-66), NTU

Abstract

The integration of physical systems with networked sensing, computation networks, and embedded control with actuation has led to the emergence of a new generation of engineered systems, the Cyber-Physical Systems (CPS). Such systems emphasize the link between cyber space and physical environment (i.e., time, space, and energy). CPS represents the next generation of complex engineering systems. They are large scale dynamic systems that offer significant processing power while interacting across communication networks.

RFID was one of the early technology that facilitated interfacing the physical world with the cyber space. RFID was mainly developed to monitor and track objects in real time. The RFID applications in CPS systems are more sophisticated and appealing. As a matter of fact the emergence of CPS has given RFID a new life.

CPS will help to solve the grand challenges of our society, such as, aging population, limited resources, sustainability, environment, mobility, security, health care, etc. Applications of CPS cover a wide band of economic, medical, and entertainment sectors. It includes; Transportation: automobiles, avionics, unmanned vehicles and smart roads; Large Scale Critical Infrastructure: bridges, mega buildings, power grid, defense systems; Health Care: medical devices, health management networks, telemedicine; Consumer Electronics: video games, audio/video processing, and mobile communication.

Building Cyber-Physical Systems is not a trivial task. The difficulty arises from the existing gap in modeling and computing of the physical and cyber environments. The design process require new theories, models, and algorithms that unify both environments in one framework. None of the current state-of-the art methods are able to overcome the challenges of developing the unified CPS design paradigm.

Several of these issues will be discussed in this talk. Case studies of real world CPSs will be illustrated.

Stereo Video Retargeting: Bringing the Theater Experience into Our Home

Prof. Chia-Wen Lin, National Tsing Hua University, Taiwan

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

“Sponsored by the IEEE Circuits and Systems Society under its Distinguished Lecturer Program”

Date : 07 August 2019 (Wednesday)
Time : 09.30 AM - 10.30 AM
Venue : Meeting Room C (S1-B1C-111), NTU

Abstract

The popularity of stereo images/videos and various VR/AR display devices poses the need of resizing stereo image/video pairs. Nevertheless, traditional resizing methods like uniform scaling and cropping usually lead to annoying shape and depth distortions such as depth change and window violation. Although content-aware retargeting schemers can address such problems, existing content-aware methods often incur conflicts among the requirements on shape, depth, and temporal coherency preservation, thereby failing to meet one or more of these requirements. This can significantly degrade the quality of experience when watching at 3D movie at home. In this talk, we will introduce our recent results on how to simultaneously avoid shape and depth distortions as well as maintain the temporal coherency of shape and depth while resizing a stereo image/video to the desired size. Different from the existing methods, our method effectively avoids the conflicts among depth, shape and temporal-coherency requirements by relaxing the resizing constraints on those regions in a 3D scene that cannot be perceived by human eyes to maintain the temporal coherency of the remaining regions. Based on this new finding, our method employs depth information to derive effective temporal-coherency constraints so as to offer visually pleasing results and achieves significantly better retargeting performance than existing methods, making it possible to bring the theater experience into our home.

Towards Global Rate Distortion Optimization in Video Coding: Recent Developments

Prof. Ce Zhu, University of Electronic Science and Technology of China, Chengdu, China

Organized by IEEE Circuits and Systems Singapore Chapter & Centre for Infocomm Technology (INFINITUS), School of EEE, NTU

“Sponsored by the IEEE Circuits and Systems Society under its Distinguished Lecturer Program”

Date : 07 August 2019 (Wednesday)
Time : 10.30 AM - 11.30 AM
Venue : Meeting Room C (S1-B1C-111), NTU

Abstract

The past decades have witnessed great advancement of video coding techniques and their wide applications in video storage and communications, where rate-distortion optimization (RDO) plays a crucial role to maximize coding efficiency in video coding. In the current block-based hybrid video coding framework, the RDO is typically performed on the block level individually and independently, which is far from being optimal as it ignores the strong spatial-temporal dependency. However, a global RDO problem becomes so complex that the processing of each coding unit is dependent and entangled with each other due to the extensive use of spatial-temporal predictions in video coding. In the talk, I will discuss the challenges of achieving global RDO in one-pass video coding and present our recent work considering the temporal dependency on top of the video coding standards H.264/AVC and HEVC, respectively.
