Image coding using feature map finite-state vector quantization

A vector quantization (VQ) scheme with finite memory called feature map finite-state vector quantization (FMFSVQ) is presented. The FMFSVQ takes advantage of good topological ordering so that the design of state codebooks is simplified. Our FMFSVQ also has no duplication of state codebooks, no synchronization required between encoder and decoder, and a very simple decoder. An adaptive FMFSVQ scheme is also proposed. Experimental results are presented for different super codebook sizes and different state codebook sizes.
