基于正交多小波变换的快速分形图像编码

提出了一种快速分形图像编码算法。编码时，通过插值正交多小波变换将原始图像缩小，然后使用摹本分形编码算法进行压缩；解码时，使用基本分形解码算法进行解码，然后使用插值正交多小波变换恢复图像。实验结果表明，与直接使用分形编码方法卡爿比，该方法缩短了编码时间，并且在信噪比、压缩比等方面得到了改善。

Faster compress image coding based on interpolatory orthonormal multiwavelets

Long coding time is the main problem in image compression based on fraetal at present, mainly due to its heavy computation of searching the best-match domain block for each range block. A fast compress image coding algorithm is proposed. At coding, the interpolation based on orthogonal multi-wavelets is used to compress the original image, and then use the basic fracta] coding algorithm to compress, during decoding, the use of the basic fractal decoding algorithm to decode, and then use interpolation orthogonal multi-wavelet transform to restore the image. Experimental show that compared with directly fractal code, this method reduces coding time, and signal to noise ratio, compression ratio, etc. Have improved.
