说明: 们讨论图像的重构。我编写的重构程序中,为了比较分解图像和重构图像,首先绘出经过小波分解的图像,然后再进行重构。在绘制分解图像和重构图像的过程中,要注意数据格式的转换。(Image Reconstruction discussed. I prepared reconfiguration process, in order to compare decomposition of images and reconstruction of images, first of all draw after a wavelet decomposition of the image, and then reconstructed. Decomposition in the rendering image and reconstructed image of the process, attention should be paid to data format conversion.)
