The convolution of two vectors, u and v, represents the area of overlap under the points as v slides across u. Algebraically, convolution is the same operation as multiplying polynomials whose coefficients are the elements of u and v. Let m = length (u) and n = length (v). Then w is the vector of length m+n-1 whose k th element is
所以conv2和filter2类似,多维图像(RGB等)要用imfilter。 【2】 二维卷积的算法原理比較简单,參考随意一本数字信号处理的书籍,而matlab的conv2函数的滤波有个形状參数,用以下的一张图非常能说明问题: 这里给出一种最原始的实现方案。

This MATLAB function returns the convolution matrix, A, such that the product of A and an n-element vector, x, is the convolution of h and x.
Note that matrix indices in MATLAB software always start at 1 rather than 0. Therefore, matrix elements A(1,1), B(1,1), and C(1,1) correspond to mathematical quantities a (0,0), b (0,0), and c (0,0). Examples Example 1 For the 'same' case, conv2 returns the central part of the convolution.

Two-dimensional linear filtering is implemented in Matlab with conv2. Unfortunately, conv2 can only handle filtering near the image boundaries by zero-padding, which for images is usually inappropriate. To work around this, we can pad the input image and then use the 'valid' option when calling conv2. The following M-function does this ...

'Same' is the part of the output signal where the moving kernel's central element overlaps some part of the signal. So it includes signal where the central element of the moving kernel overlaps an element of the input signal and includes locations where the kernel "falls off" the end of the signal as long as the central element is still over the input signal.
