How to smooth an edge ?

Hi,

I need to smooth the edge of an image but I don't know if does a Matlab function exist for that.

Any idea ?

Thanks.

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

1. detect the edges using the original image, then
2. create an edge mask that defines the location of the edge pixels, then
3. blur the whole image, then
4. 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?

Thank you for the answer!

What I want to do is to smooth the edges of a left ventricular to track its displacement. I'll try to implement what did you suggest and keep you informed.
