Efficient Inter-Band Prediction and Wavelet Based Compression for Hyperspectral Imagery: A Distributed Source Coding Approach
Hyperspectral images have correlation at the level of pixels; moreover, images from neighboring frequency bands are also closely correlated. In this paper, we propose to use distr...

A Rate-Distortion Approach to Wavelet-Based Encoding of Predictive Error Frames
In this paper, we develop a framework for efficiently encoding predictive error frames (PEF) as part of a rate scalable, wavelet-based video compression algorithm. We investigate ...

ROI and FOI Algorithms for Wavelet-Based Video Compression
Abstract. Many techniques make great contributions to video compression with removal of spatial and temporal redundancy in and between frames. However, compressed video is still ra...

Multiple-Description Wavelet based Image Coding
Abstract--We consider the problem of coding images for transmission over error-prone channels. The impairments we target are transient channel shutdowns, as would occur in a packet...
