I'm working on the mammogram and trying to locate the nipple locations. Sometimes nipple is quite small, it may be in the breast boundary or outside of the breast, so I feel quite difficult to locate it. What I'm thinking is an algorithm to output the coordinates of the nipple pixels in the mammogram picture. Please advise what I shall do. Many thanks

Hi. Did you finally find an algorithm for your work?

I'd probably try to threshold the whole thing and then get a smoother envelope using activecontour(). I attach a demo. Then XOR the two binary images and take the biggest blob with bwareafilt() (to get rid of any small noise or small things outside the envelope. This won't work for mammograms with missing nipples though, only ones where the nipple sticks out beyond a very smooth boundary.
Star said it's pretty rare to do this -- why do you need to do it?

With anything medical, your best option is to start with PubMed. There isn’t a lot published on nipple identification and segmentation, but when I searched with the search string (nipple & segmentation & mammogram) & english[la], I pulled up eight articles. Only one is free, but you can probably get all of them online with your university account or through your university library.
Searching with (nipple & location & mammogram) & english[la] pulled up 45 but they didn’t all look as relevant. Experiment with other search strategies.
Click on ‘Display Settings’ at the top, and choose ‘Abstract’, ‘200’ and ‘Pub Date’ for the most useful display. (I right-click on ‘Related citations’ under the article abstract and open it in a new tab if I find an interesting article.)

Another good reference is Vision Bib which is a bibliography of nearly all image processing articles ever published (or so it seems).

And searching it on a standard search engine will probably get me in trouble with work...!
