摘要
小波变换是图像压缩中的一个重要工具。二维图像在进行压缩变换时,因变换后系数需要进行截短,以及小波与图像可能不是最优匹配,因此使得重构后的图像能量损失较大。为了减少重构后图像能量损失,本文提出了顺序组合最优匹配小波构造方法;通过Woman图像,构造该图像的顺序组合最优匹配小波,并用该小波对其图像进行处理,最后与其他一些方法进行比较处理结果。
The wavelet transformation is an important tool in image compression . When an two-dimensional image carries on the compression transformation, after the transformation the coefficient must be shortened, as well as the wavelet and the image are not possibly the most superior matches, so this causes the image energy of restructuring to lose in a big way. In order to reduce the image energy of restructuring, this article proposes the method of the order compose of most superior match wavelet; Through the Woman image, the image of order compose of most superior match wavelet is structured and processed by the wavelet, and finally the processing result is compared with other methods.
