space using the spatial sharpness enhancement technology scalable compression schemes

摘要

A kind of video encoder/decoder use space scalable compression scheme use space sharpness enhancement techniques are disclosed. The video compression scheme introduces several different video enhancement techniques to base. One image analyzer determines the best mixing of best or various video enhancement techniques. It is involved in the mixing and original full resolution input signal of the more selected video enhancement techniques of analyzer, to determine which pixel or pixel group need a residual enhancement layer. The mixed transport of the selected video enhancement techniques of parameter definition is to decoder layer, so that the mixing of identical video enhancement techniques can be used for decoder layer.
