Fast bintree-structured image coder for high subjective quality
A practical, fast, bintree-structured variable size block image coder is proposed. The inability of current segmentation-based image coding methods using piecewise functional approximation to represent textures is overcome by a generalized BTC encoding of approximation errors in texture areas. This new texture encoding technique significantly enhances subjective image quality at small extra costs to compression ratio and algorithm complexity.<<ETX>>
