4th conference on wavelet applications in signal and image processing
作者: Yaroslavsky, LP TEL AVIV UNIV FAC ENGN DEPT INTERDISCIPLINARY STUDIES IL-69978 TEL AVIV ISRAEL
On the base of local criteria of processing quality, a class of local adaptive linear filters for image restoration and enhancement is introduced. the filters work in a running window in the domain of DFT of DCT and h... 详细信息
