摘要
A method and apparatus for compressing one or more blocks of pixels using a Haar wavelet transform and a preferential quantization and scaling routine to produce one or more respective words comprising preferentially quantized Haar wavelet coefficients and associated scaling indicia. Within the context of an MPEG-like processing system, memory resource requirements, such as for frame storage, are reduced by a factor of two. In another embodiment, each pixel block is subjected to discrete cosine transform (DCT) processing and high order DCT coefficient truncation, thereby effecting an improved compression ratio of the pixel information.
