Abstract: Aiming to the weakness of long encoding time of traditional fractal coding method，a quick fractal image coding method is presented called LSS（Local Sub Search）.Experimental results have shown that compared to the traditional coding method on a true color image，the approach can reduce encoding time efficiently in similar PSNR and compression ratio.The proposed method has been realized under the VC++6.0 Integrated Development Environment（IDE）.

摘要： 针对分形图像编码时间过长的缺点，提出了一种快速分形图像编码方法，称为LSS（Local Sub Search），实验结果表明，对于真彩图像，较之传统的分形编码方法，该方法在相近的压缩比和解码图像质量的情况下，编码时间大为缩短。该方法已在VC++6.0集成开发环境下得以实现。
