Wavelet compensation algorithm based on fractal image coding
Jian Jiang Lu, Zhongxing Ye, Yuru Zou · Computer Engineering and Applications Journal · 2007
A new image coding algorithm for combining fractal and wavelet transformation is presented.The spatialtrends of a image is encoded by fractal coding algorithm,and itsanomalies(such as edge information) used for compensation for the trends is extracted by wavelet transformation.Since the detail coefficients generated by wavelet transformation are encoded on the basis of their significance,the new coding method,like EZW,allows the encoding or decoding to stop at any point.The experimental results show that the method proposed is better than adaptive quadtree fractal coding algorithm and wavelet transformation coding algorithm.
