We study the use of low-density generator matrix (LDGM) codes for lossy compression of the Bernoulli symmetric source. First, we establish rigorous upper bounds on the average distortion achieved by check-regular ensemble of LDGM codes under optimal

We consider a set of S independent encoders that must transmit a set of correlated sources through a network of noisy, independent, broadcast channels to T receivers, with no interference at the receivers. For the general problem of sending correlate

In this paper, we describe and analyze the source and channel coding properties of a class of sparse graphical codes based on compounding a low-density generator matrix (LDGM) code with a low-density parity-check (LDPC) code. Our first pair of theore

The impact of side information about the distortion measure in problems of quantization is analyzed. It is shown that such "distortion side information" is not only useful in general, but that in many cases knowing it at only the encoder is as good a

We consider transmitting a source across a pair of independent, nonergodic channels with random states (e.g., slow-fading channels) so as to minimize the average distortion. The general problem is unsolved. Hence, we focus on comparing two commonly u

We introduce a novel source coding problem, compound conditional source coding. We describe how a number of media coding problems can be cast into this framework. We develop the achievable rate region for this problem and error exponent results. We s

The compression of multiview video in an end-to-end 3D system is required to reduce the amount of visual information. Since multiple cameras usually have a common field of view, high compression ratios can be achieved if both the temporal and inter-v

We describe a method to encode fingerprint biometrics securely for use, e.g., in encryption or access control. The system is secure because the stored data does not suffice to recreate the original fingerprint biometric. Therefore, a breach in databa

We consider multiview video compression: the problem of jointly compressing multiple views of a scene recorded by different cameras. To take advantage of the correlation between views, we propose using disparity compensated view prediction and view s

We describe the architecture for our distributed video coding (DVC) system. Some key differences between our work and previous systems include a new method of enabling decoder motion compensation, and the use of serially concatenated accumulate syndr
