Vector subband coding of images
John P. Wus · 1994
Subband coding has proven to be a very effective technique when used for image compression purposes. The concept of a 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 described. Detailed vector formation, filtering processes, vector codebook generation, vector encoding and decoding, and the parameters used in the coding scheme are examined. Finally, the test results are presented along with future directions of the work.
