Well, you can blur the whole image with imfilter or conv2.
If you want only the edge blurred, then you're going to have to
- detect the edges using the original image, then
- create an edge mask that defines the location of the edge pixels, then
- blur the whole image, then
- replace the edge pixels only with the corresponding pixels from the blurred image.
out = originalImage
out(edgeMask) = originalImage(edgeMask);
What do you want to do?
