Image Classified Vector Quantization

An image vector quantization (VQ) on 4x4 blocks of pixels using edge classification is explained. For each class a subcodebook using LBG algorithm is designed. An initial codebook is generated using the binary splitting techniques. The results of vector quantization with and without classification for 0.56 and 0.6785 bits per pixel are compared.
