The color video coded method of being based on ueburetsuto disassembly

摘要

(57) Abstract As for this invention, 4:2: It regards the color video coded method of being applied to the color space which is formed brightness plane surface Y of 0 formats and color difference plane surface U and by V using generally known 3D-SPIHT algorithm. The ueburetsuto disassembly of U and V plane surface, extending to the number of resolution levels which pulled 1 from the number of resolution levels of ueburetsuto disassembly of brightness plane surface, it is done. All the resolution colors U or you can see V plane surface as an approximation of all resolution of brightness plane surface, the aforementioned all the resolution colors U or size of V plane surface is the same as the size of 1st level approximation with multi resolution disassembly of Y plane surface, n next resolution level of brightness (n-1) of color difference has the same size as the next level. With the resolution whose Y plane surface is lowest it is related each pixel (i, j) of the approximate sub - band, to the pixel of that at the same position inside the sub - band to which U and V plane surface correspond.
