Fractal based compression techniques  which provide a large compression ratio for grayscale images have been reported in the literature. Fractal coding is based on the fractal theory of iterated transformations. But  it's searching and mapping algorithm cannot address the need of real-time. To improve the real-time performance of the algorithm  we use wavelet transforms to decompose images. The wavelet transform is a natural tool for analyzing fractal block coders since wavelet bases possess the same type of dyadic self-similarity that fractal coders seek to exploit. We propose a method of fractal coding the weighted wavelet subtree. Experimented results show that the improved hybrid image can improve the PSNR of the rebuild image at the same compression ratio.   Global superconvergence for blending surfaces by boundary penalty plus hybrid FEMs 期刊论文  OAI收割 APPLIED NUMERICAL MATHEMATICS, 2001, 卷号: 39, 期号: 1, 页码: 61-85 作者:  Li, ZC;  Yan, NN   |  收藏  |  浏览/下载：12/0  |  提交时间：2018/07/30 blending surfaces  biharmonic equation  bi-cubic Hermite element  boundary penalty methods  boundary hybrid techniques  superconvergence  stability
