Abstract
Image encoding apparatus and methods include recursively decomposing the luminance values of sequential frames into spatio-temporal spectral components, by quadrature mirror filter (QMF) processing of the luminance values. The filtered signals are subsampled, and each decomposed level of the spectral components is coded by vector quantization.
