Block of the moving compensating forecasting singular value expansion

摘要

PROBLEM TO BE SOLVED: To provide a movement compensation prediction singular value development encoding device which is capable of encoding with higher efficiency, as compared with the conventional encoding devices.;SOLUTION: An SVD movement detecting part 1 applies SVD transformation of prediction error between a block A of a present image and a plurality of prediction image blocks of a precedent image which have been previously determined, the amount of codes is obtained by performing quantization and entropy encoding of the SVD transformation results, and obtains an SVD transformation base, for the predictive image block is which the amount of codes is minimum, and moving vectors MV. The SVD transformation base is sent to an SVD orthogonal transformation part 4 and an inverse SVD orthogonal transformation part 8. The moving vectors MV are sent to a movement compensation predicting part 2 and a receiver side. The predictive error, obtained by a subtraction part 3, is subjected to SVD orthogonal transformation by the transformation part 4, and is further subjected to quantization an entropy encoding, and outputted. The SVD transformation base which is used in the transformation part 4 can be regenerated on the receiving side, so that there is no need for transmission to the receiving side.;COPYRIGHT: (C)2002,JPO
