Linear and non-linear approximation with wavelets Linear approximation is obtained by keeping M low frequency coefficients and then applying the inverse wavelet transform. Here we take M=n^2/4 by keeping n/2 x n/2 low frequency coefficients. Lin

图像融合，实现两幅图像的特征融合.该程序使用小波分解的方法先对两幅图像进行小波分解，然后进行多种方法对图像进行特征融合-Fusion, feature fusion of two images to achieve. The method uses wavelet decomposition of the two images before wavelet decomposition, and then features a variety of methods of image fusion

The fusion of images is the process of combining two or more images into a single image retaining important features from each of the images. A scheme for fusion of multi-resolution 2D gray level images based on wavelet transform is presented in this
