17-9 冗長DCTを用いた雑音除去法の性能改善(第17部門画像符号化2)

抄録

Authors previously proposed the noise removal method that used redundant DCT and the Color-Shrinkage. In our noise removal method using redundant DCT, plural numbers of noise removal results are obtained in the process. This paper shows that improvement can be obtained by replacing the previous average operation with the aggregation operation.
