Title Anisotropic diffusion as a preprocessing step for efficient image compression
Abstract Anisotropic diffusion was introduced in image processing as an image enhancement method. It is a non-linear smoothing process which intends to remove irrelevant or false details while preserving the edges, i.e. it "extracts" the essential visual information. The paper proposes a useful application of anisotropic diffusion in image data compression. We tried to show that for high compression a preliminary anisotropic diffusion on the image yields a better result after coding. This is an important achievement in view of low bit rate transmission.
