Abstract
Subband coding has proven to be a very effective technique when used for image compression purposes. In this paper, the concept of Vector Filter Bank (VFB), which extends the conventional Scalar Filter Bank (SFB) to the vector case, is introduced. A new image coding algorithm, called Vector Subband Coding (VSC), is proposed. Detailed vector formation, filtering processes, vector codebook generation, vector encoding and decoding are examined. Finally, the test results are presented
