摘要 论文提出了一种新的基于斜变换的形态小波变换的思想和算法,将该方法与现存文献中所提出的非线性形态学小波分析方法进行了比较分析并应用于图像压缩,通过计算机仿真试验说明,提出的方法为小波分解后的图像提供了更为灵活的组合方式,对图像的压缩比CR以及峰值信噪比PSNR的变化范围能够精确地调控,从而在保证图像质量良好的情况下获得更大的压缩比。 The paper introduces a new morphological wavelets based on slant transform,Comparing with the wavelets introduced by existing literature,The computer simulation result shows this new scheme provides a more vivid and efficiency way to handle image,it can control compression ratio and PSNR of images accurately and attain good reconstructed image while assuring satisfying compression ratio.
