摘要 图像分形编码处理数据较多、压缩编码时间过长。论文提出了一种快速图像处理算法,对低频子图进行分形编码,以缩短图像压缩编码的时间,然后采用低频差值,对图像实施压缩感知编码来获取解码之后包含的图像内容信息。实验结果表明本文算法可以提高图像分形编码速度,改进重构图像的解码质量。 Aiming at the too much data in image fractal coding the too much time in image compression encoding,the paper proposes a fast image processing algorithm to solve the problems.The algorithm only implements image fractal coding to low-frequency sub-images,which effectively reduces the time of image compression encoding.The decoded image information can be obtained after adopting the low-frequency difference to implement compressed sensing encoding to images.Experiment results show that the proposed algorithm can increase the image fractal coding speed and improve the decoding quality of reconstructed images.
