A Visual Model Weighted Cosine Transform for Image Compression and Quality Assessment

摘要: Utilizing a cosine transform in image compression has several recognized performance benefits, resulting the ability to attain large ratios with small quality loss. Also, incorporation of model human visual system into an or assessment technique intuitively should (and often proven to) improve performance. Clearly, then, it prove highly beneficial combine model. In past, combining these two been hindered by fundamental problem from scene alteration that is necessary for proper utilization. A new analytical solution this problem, taking form straightforward multiplicative weighting function, developed paper. This readily applicable and conjunction transform. development, relevant aspects are discussed, refined version mean square error measure given which increase measure's utility.
