【摘要】 本文基于分形图像编码的思想,以图像块的分形维数对图像块分类,并对不同类块采用不同编码。实验表明该分类方法能够准确描述图像块的纹理特征,基于该分类的图像压缩编码方法,在信噪比较高的条件下,大大提高了编码速度,且压缩比有所提高。更多还原

【Abstract】 In the paper ,based on the idea of classified fractal image coding ,an image compression coding method is presented. Using the fractal dimension of fractal geometry space as the characteristic parameter ,the image blocks are classified and different coding methods are used for the different image blocks. The experiment results indicate that the method can exact to classify the image blocks and the coding speed is raised much more times, at the same time , the compression ratio is raised more which the PSNR is not almost change .更多还原
