Báo cáo hóa học: "Research Article Morphological Transform for Image Compression" ppt

... method for image compression based on morphological associative memories (MAMs) is presented. We used the MAM to implement a new image transform and applied it at the transformation stage of image ... we present a new image transform applied to image compression based on MAMs. For image compression purposes, we used heteroassociative MAMs of minimum type at the transform...
