摘要： The present disclosure relates to a multi-plane image encoding technology for adaptively determining the encoding sequence of planes in the image based on the characteristics of the image to be coded, and provides a multi-plane image encoding apparatus including a plane encoding sequence determiner for adaptively determining a sequence of multiple color planes inputted in a predetermined unit based on the encoding cost; and an encoder for encoding the multiple color planes inputted by the predetermined unit in the determined sequence. Encoding the multi-plane image with the sequence of the planes in the input image determined by the image characteristics enables an increased efficiency of encoding over conventional fixed plane sequence encoding, providing a particularly higher encoding efficiency when performing predictions between the planes.

摘要： A video encoding apparatus includes an intra prediction error collector; a transform base generator; an intra predictor; and a transform encoder, the intra prediction error collector collecting prediction errors of blocks having an equal intra prediction mode from macroblocks in a regular unit, which are encoded prior to a current macroblock, the transform base generator generating transform bases for respective intra prediction modes based on the prediction errors collected by the intra prediction error collector. Accordingly, the intra prediction encoding performance can be significantly improved with adding no addition information by adaptively generating a transform base according to an image characteristic change and transform-encoding an intra prediction error. As a result, the compression efficiency of a video compression apparatus or the picture quality of a reconstructed image can be greatly improved.
