I segment a mammography breast image but the border of it is not accurate. I also have canny output of the image. now, I want to expand breast region to outer border of canny, but I do not know how to do it? I insert the output of breast segmentation and canny output below. I want to expand segmentation to outer border of canny. can you help me?

Why did you use canny anyway? Why not just threshold? Or maybe you can use activecontour() for a smoother outline.

Zero out the pixelCount(1). There's something weird about the histogram so it's not finding the right threshold. It's because the second bin is zero and the first bin is real high. Zeroing out the first bin will fix that.
