User defining image filter

2 views (last 30 days)
I have a problem where I have to input an image and a kernel and it must give an output image. The kernel could be of any type. I have been trying various techniques. Could be really helpful if somone could post the code of imfilter in a readable way or maybe give some kind of a code as per the problem statement which would help me understand my mistake.

Did you try something like
grayImage = imread('moon.tif');
kernel = ones(31) / 31^2;
filteredImage = imfilter(grayImage, kernel);

If you need to avoid built-in functions like imfilter() and conv2() for some reason (WHY????), see my "manual" version of convolution.
