HIERARCHICAL FINITE-STATE VECTOR QUANTIZATION FOR IMAGE-CODING

The hierarchical finite-state vector quantization (HFSVQ) introduced i n this paper is an improvement of the finite state vector quantization combined with hierarchical multirate image coding. Based on an unders tanding of the perception of human eye and the structural features of images, the HFSVQ technique employs different coding rates and differe nt numbers of the predictive states for representative vector selectio n. The bit rate used to encode images is very low while the reconstruc ted images can still achieve a satisfactory perceptual quality.
