Image compression and decompression

摘要: Clusters of pixels are defined for use in image compression and decompression. The information used to define the clusters may include pixel values at predetermined positions relative a or related motion vectors, gradients, texture etc.. During images is examined determine cluster which it belongs. Thus can be classified according their information. In an embodiment definitions selected dynamically, dependent on content. For each control parameter set computed post-processing operation, such as filter coefficients filtering statistical data locally generating texture. content so that, when operation applied after decompression will improve quality that belonging cluster. compressed sets transmitted apparatus. Upon decompression, represents decompressed classify different locations pixels.
