Imfilter a h
Witryna9 cze 2024 · Try imfilter() function. B = imfilter( A , h ) filters the multidimensional array A with the multidimensional filter h and returns the result in B . Refer to the following documentation link on imfilter function: Witryna5 paź 2011 · out = imfilter(a,h, 'conv'); 2) By default, conv2 gives the full filtered result. This is different than the default behavior of imfilter, which yields the output as the same size as the input. Both conv2 and imfilter provide optional arguments which can be used to get either result, which is to say: ...
