主  题:Image coding 

摘      要:A modified version of the Bezier-Bernstein polynomial approximation technique has been developed which gives local control of data points depending on an absolute error criterion. Based on this concept, two algorithms for coding a gray-tone image have been formulated. Error bounds have been developed which are used to approximate gray segments of pixels. These bounds are determined by the desired error in approximation. Effectiveness of the algorithms has been demonstrated on a set of images.
