| 摘 要： | 在分析小波包变换和分形编码特点的基础上,先将图像进行小波包分解,对进一步细分的高频部分直接进行频域截断,对低频部分进行分形压缩.计算机模拟试验表明,上述方案与基本分形编码方法相比,在重建图像主观质量和运行时间上都显示出优越性.

| Abstract: | By analyzing the merit and disadvantage of basic fractal image algorithm and wavelet package transformation,a new fractal image encoding algorithm was proposed.Firstly the image is decomposed by the wavelet package,then the high frequency part is compressed by wavelet transformation,which utilizes the characteristic of wavelet package analysis;at the same time the low frequency part is compressed through fractal coding technique.Computer simulation shows that the proposed method shows better performance on ... |
