The decoding vessel and the be adapted block phenomenon removal decoding manner which possess be adapted block phenomenon removal function

摘要

Abstract Topic At the time of dispersion cosine converting, on the scope mosaic model/imitationWith the way the be adapted block reality which removes the block phenomenon which appearsIt regards the decoding vessel which possesses elephant removal function. Solutions Be adapted block phenomenon removal function of this inventionAs for the decoding vessel which it possesses, the buffer 71 which stores the compressed signalWith, the dynamic vector signal trust of the three-dimensional frequency domain which is quantizedThe variable decoding vessel 72 which outputs the number and, the space which is quantized lapThe 8*8 converse quantizer which accomplishes converse quantization to the signal of the wave number fieldJudging whether or not there is a necessity of 73 and three-dimensional frequency component presumption,With the block phenomenon judgment vessel 77 which it does and the three-dimensional frequency domain the bodyThe boundary detector 78 which judges boundary and, be adapted three-dimensional cycleThe adaptation space which presumes several components low frequency presumption vessel 79 and the space lapThe 8*8 converse separation which converts the signal of the wave number field to the signal of the pixel fieldScattering cosine converter the dynamic compensator 75 which accomplishes 74 and the dynamic compensationWith, the frame memory 76 which stores the signal of the pixel fieldIt features that it includes.
