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