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.此快速方法充分利用了分形中迭代函数系统的吸引子的分辨率与尺度无关的特性,将原始图像缩小后进行压缩,从而加快了编码的速度.实验结果表明,较之传统的分形编码方法,此方法在相近的解码图像质量和压缩比的情况下,编码时间大为缩短.
Aim to the weakness, long encoding time, of traditional fractal coding method, a quick fractal image coding method is presented. The method makes the best of the theorem of Resolution independent in fractal theory. Through encoding the reduced image of the original image, it improves fractal image compress performance. Experimental results have shown that compared to the traditional coding method, the approach can reduce encoding time efficiently in similar PSNR and compression ratio.
