Abstract
A data compression system (200) employs an encoder (210) optimized to decorrelate and make independent from the original signal (202), the quantization noise produced during signal compression by a quantizer (214). Because the quantization noise produced during signal compression is made independent from and orthogonal (i.e., uncorrelated) to the original signal (202), filtering is achievable by filter (223) which is an adaptive oriented uncorrelated Weiner (AOW). The filter (223) adaptively selects a filter mask from a plurality of available filter masks. Mask selection is based, in part, upon either filter orientation or generation of a minimum variance output. Image component processing is performed on a local (e.g., pixel-by-pixel or 2-by-2) basis as opposed to a global basis (e.g., across the entire image).
