On the non-optimality of four color coding of image partitions
Recent interest in region based image coding has given rise to graph coloring based partition encoding methods. These methods are based on the four color theorem for planar graphs...

Distributed Functional Compression through Graph Coloring
We consider the distributed computation of a function of random sources with minimal communication. Specifically, given two discrete memoryless sources, X and Y , a receiver wishe...

A proposal for high compression of faces in video sequences using adaptive eigenspaces
This paper presents a proposal for a novel video coding scheme intended to encode human faces in video sequences at very high compression using a recognition and reconstruction ap...

Watermarking of MPEG-2 video in compressed domain using VLC mapping
In this work we propose a new algorithm for fragile, high capacity yet file-size preserving watermarking of MPEG-2 streams. Watermarking is done entirely in the compressed domain,...

Analysis and Evaluation of Address Arithmetic Capabilities in Custom DSP Architectures
—Many application-specific architectures provide indirect addressing modes with auto-increment/decrement arithmetic. Since these architectures generally do not feature an indexe...
