“…[3,4,5,6,7]), most of the early works do not consider applications in image compression. Only recently it has been shown that edge-or segment-based homogeneous diffusion approaches can beat JPEG 2000 for cartoon-like im-1 ages [8], as well as for depth maps [9,10,11]. Apart from these linear, featurebased approaches, there are some attempts to use nonlinear PDEs for image compression.…”
