Visual-Weighted DCT Coding for Monochrome Still Images
흑백 정지 영상의 시기 하중 DCT 부호화
Abstract
HVS based transform coding techniques for still images take the lowest spatial frequency and luminance contrast sensitivity as the most crucial factors in determining the image quality perceived by human eye. Only the frequency weighting has been main issue. The proposed Weighted Discrete Cosine Transform (WDCT) has the lowest frequency of about 4 [cyc/deg] in 8
