|Abstract:||Edges are one of the most perceptually important features in images that provide geometric information to views to distinguish objects in a scene. Wavelet based coding algorithms have been successful in image compression, but like classical cosine transform methods, they are unable to provide a good representation of 2D edges. Cel-based animation sequences, or cartoons, contain predominantly edge information. Although these types of images are relatively less complex than real-life images, the geometrical structures within the cel images challenge even the most complex wavelet-based coders. Wedgelets and beamlets are able to capture geometrical structures in images more efficiently than wavelets. In this paper, we propose a novel hybrid image coder that utilizes both wavelets and wedgelets to code cartoon images. Our prototype coder demonstrates significant improvements in visual quality of wedgelet beamlets coded cartoon images over standard wavelet-based coding techniques.|
