Title: An overview of image/video compression down the history lane
Speaker: Professor Oscar C. Au
Affiliation: Hong Kong University of Science and Technology
In this plenary overview talk, I will take the audience to take a brief walk down the history lane to review the various developmental stages of image and video compression standards, including MPEG-1, MPEG-2, MPEG-4, H.261, H..263, H.264, and the latest HEVC video standards, and JPEG and JPEG 2000 image standards. Key features of the latest standards will be introduced. Major industrial and commercial applications such as digital TV broadcasting, set-up box, DVD, Blu-Ray, multi-media enabled smart phone, PMP, video conferencing, digital camera, etc. will be highlighted. I will also briefly describe the exciting and challenging game of standard.

Talk #2

Title: Radiometric Compensation for Ubiquitous Projection
Speaker: Homer H. Chen
Affiliation: National Taiwan University, Taiwan
Integrating pico-projectors in mobile and wearable devices allows nearby walls, desks, or bodies to be conveniently used as projection surfaces. Ubiquitous projection is no longer a fiction. Although the miniature of projection technology brings about new form of social interaction and augmented reality, ubiquitous projection is not free of challenges because the ad hoc projection surfaces are not as perfect as the regular projection screens. This paper discusses the technical issues of and solutions for mobile projectors, particularly in the area of radiometric compensation. It provides an overview of the calibration techniques for static and moving pico-projectors and the techniques for combating the physical limitations of projectors and cameras in brightness and dynamic range. Suggestions of future research are also provided.

Title: 3D Video: Some Challenging Topics
Speaker: Professor Hsueh-Ming Hang
Affiliation: National Chiao Tung University, Taiwan
3D films have a history of a few decades, but only recently 3D video consumer products are gradually becoming popular. The next negation of 3D research focus is on the so-called virtual-viewpoint (or free-viewpoint) video system. It is also an on-going standardization item in the international ITU/MPEG Standards. In addition to the movie special effects, one application of virtual-view system is the multi-view auto-stereoscopic (glasses free 3D) display. Typically, a densely arranged camera array is used to acquire input images and a number of virtual view pictures are synthesized at the player using the depth-image based rendering (DIBR) technique. Three essential components are needed for building a virtual-view system: depth estimation, data compression, and view synthesis. Another issue is how human being judges the quality of 3D video. There exist a number of 2D image/video quality assessment models, but the 3D perceptual modeling is largely under development. We will give a quick overview of these challenging topics and summarize their recent progresses.

Talk #4

Title: An introduction to Graph Signal Processing
Speaker: Professor Antonio Ortega
Affiliation: University of Southern California
Graphs have long been used in a wide variety of problems, such analysis of social networks, machine learning, network protocol optimization, decoding of LDPCs or image processing. Techniques based on spectral graph theory provide a “frequency” interpretation of graph data and have proven to be quite popular in multiple applications.

In the last few years, a growing amount of work has started extending and complementing spectral graph techniques, leading to the emergence of “Graph Signal Processing” as a broad research field. A common characteristic of this recent work is that it considers the data attached to the vertices as a “graph-signal” and seeks to create new techniques (filtering, sampling, interpolation), similar to those commonly used in conventional signal processing (for audio, images or video), so that they can be applied to these graph signals.

In this talk, we first introduce some of the basic tools needed in developing new graph signal processing operations. We then introduce our design of wavelet filterbanks of graphs, which for the first time provides a multi-resolution, critically-sampled, frequency- and graph-localized transforms for graph signals. We conclude by providing several examples of how these new transforms and tools can be applied to existing problems. Time permitting, we will discuss applications to image processing, depth video compression, recommendation system design and network optimization.
