Introduction, Environmental scientists use aerial and satellite imagery to study pollution patterns. For entertainment, television bringing live pictures to our homes is a part of modern life. Classical images, drawings and paintings, have been giving human beings the enjoyment of art since the dawn of civilization.

GIDDY

Joint Compression and Classification,eads to improved compression and classification jointly. We call this algorithm the HMM VQ algorithm. Comparisons are made with BVQ, a joint compression and classification algorithm developed by Oehler, Gray, Perlmutter, Olshen, ., which is described in Section 3.4.

Vector Quantization, contains 176 × 144 pixels. Each pixel is described by one luminance component and two chrominance components, each stored originally in 1 byte. Sin the chrominance components are subsampled every 2× 2 pixels, one image requires 176× 144 × 1.5 bytes, i.e., 304128 bits, to specify. For a video sequen

Two Dimensional Hidden Markov Model,ch as selecting block sizes dynamically ac cording to context. The improvement achieved demonstrates the potential of context to help classification. In this chapter, a two dimensional hidden Markov model (2-D HMM) is introduced as a general framework for context dependent classifiers.
