Coding into a source: a direct inverse Rate-Distortion theorem
Shannon proved that if we can transmit bits reliably at rates larger than the rate distortion function R(D), then we can transmit this source to within a distortion D. We answer th...

Rate distortion bounds on passive sonar performance
Abstract-- Information theory provides a novel perspective on passive sonar performance analysis. This approach begins by partitioning the search space and then considers the probl...

A Fast Downsizing Video Transcoder for H.264/AVC with Rate-Distortion Optimal Mode Decision
This paper focuses on the mode decision and motion selection problem when H.264/AVC video streams are transcoded in spatial resolution. A fast downsizing transcoding scheme is dev...

Rate-Distortion Bound for Joint Compression and Classification
- Rate-distortion theory is applied to the problem of joint compression and classification. A Lagrangian distortion measure is used to consider both the squared Euclidean error in ...

Graph-Cut Rate Distortion Algorithm for Contourlet-Based Image Compression
The geometric features of images, such as edges, are difficult to represent. When a redundant transform is used for their extraction, the compression challenge is even more dif...
