Found in: IEEE MultiMedia
By Cha Zhang,Qin Cai,Philip A. Chou,Zhengyou Zhang,Ricardo Martin-Brualla
Issue Date:January 2013
pp. 17-27
The Viewport immersive teleconferencing system reconstructs sparse 3D representations for each user and applies virtual seating to maintain the same seating geometry as face-to-face meetings.
Virtual View Reconstruction Using Temporal Information
Found in: 2012 IEEE International Conference on Multimedia and Expo (ICME)
By Shujie Liu,Philip A. Chou,Cha Zhang,Zhengyou Zhang,Chang Wen Chen
Issue Date:July 2012
pp. 115-120
The most significant problem in generating virtual views from a limited number of video camera views is handling areas that have become dis-occluded by shifting the virtual view away from the camera view. We propose using temporal information to address th...
Realistic audio in immersive video conferencing
Found in: Multimedia and Expo, IEEE International Conference on
By Sanjeev Mehrotra, Wei-ge Chen, Zhengyou Zhang,Philip A. Chou
Issue Date:July 2011
pp. 1-4
With increasing computation power, network bandwidth, and improvements in display and capture technologies, fully immersive conferencing and tele-immersion is becoming ever closer to reality. Outside of video, one of the key components needed is high quali...
Honest signals in video conferencing
Found in: Multimedia and Expo, IEEE International Conference on
By Byungki Byun,Anurag Awasthi,Philip A. Chou,Ashish Kapoor,Bongshin Lee,Mary Czerwinski
Issue Date:July 2011
pp. 1-6
We propose a novel system to analyze gestural and nonverbal cues of participants in video conferencing. These cues have previously been referred to as
Resilient Peer-to-Peer Streaming

FEC and Pseudo-ARQ for Receiver-Driven Layered Multicast of Audio and Video
Found in: Data Compression Conference
By Philip A. Chou, Albert Wang, Sanjeev Mehrotra, Alexander E. Mohr
Issue Date:March 2000
pp. 440
We consider the problem of joint source/channel coding of real-time sources, such as audio and video, for the purpose of multicasting over the Internet. The sender injects into the network multiple source layers and multiple channel (parity) layers, some o...
Three-Dimensional Wavelet Coding of Video with Global Motion Compensation
Found in: Data Compression Conference
By Albert Wang, Philip A. Chou, Sanjeev Mehrotra, Zixiang Xiong
Issue Date:March 1999
pp. 404
Three-dimensional (2D+T) wavelet coding of video using SPIHT has been shown to outperform standard predictive video coders on complex high-motion sequences, and is competitive with standard predictive video coders on simple low-motion sequences. However, o...
Multiple Description Decoding of Overcomplete Expansions Using Projections onto Convex Sets
Found in: Data Compression Conference
By Philip A. Chou, Sanjeev Mehrotra, Albert Wang
Issue Date:March 1999
pp. 72
This paper presents a POCS-based algorithm for consistent reconstruction of a signal x 2 R K from any subset of quantized coefficients y 2 R N in an N ? K overcomplete frame expansion y = Fx, N = 2K. By choosing the frame operator F to be the concatenation...
Advances in immersive communication: (1) Telephone, (2) Television, (3) Teleportation
Found in: ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)
By Philip A. Chou
Issue Date:October 2013
pp. 1-4
The last great advances in immersive communication were the invention of the telephone over 137 years ago and the invention of the video telephone (né television) over 86 years ago. However, a perfect storm is brewing for the next advance in immersive...
Pangolin: speeding up concurrent messaging for cloud-based social gaming
Found in: Proceedings of the Seventh COnference on emerging Networking EXperiments and Technologies (CoNEXT '11)
By Chao Zhang, Cheng Huang, Felix Livni, Hao Chen, Jay Thaler, Jin Li, Keith W. Ross, Philip A. Chou, Sanjeev Mehrotra
Issue Date:December 2011
pp. 1-12
The convergence of games and online social platforms is an exploding phenomena. The continued success of social games hinges critically on the ability to deliver smooth and highly-interactive experiences to end-users. However, it is extremely challenging t...
Utility maximization in peer-to-peer systems
Found in: Proceedings of the 2008 ACM SIGMETRICS international conference on Measurement and modeling of computer systems (SIGMETRICS '08)
By Jin Li, Minghua Chen, Miroslav Ponec, Philip A. Chou, Sudipta Sengupta
Issue Date:June 2008
pp. 305-305
In this paper, we study the problem of utility maximization in P2P systems, in which aggregate application-specific utilities are maximized by running distributed algorithms on P2P nodes, which are constrained by their uplink capacities. This may be unders...
