20 Mar 2014 EM-MPM Image Segmentation Algorithm Segments a grayscale image using the EM-MPM algorithm. Author: Alceu Costa

Thank you for the reference Akshay Gore.

I implemented this EM-MPM algorithm as part of an undergraduate course based on a masters dissertation of another student, so there may be differences between the algorithm described in the article and my implementation.

Here is a link to the masters dissertation (in Portuguese): http://www.teses.usp.br/teses/disponiveis/55/55134/tde-08062006-124838/pt-br.php

Hi Jonathan, can you provide a link to the image or send it via email?

This way I can check if there is a bug in my code or if the image is a case were this segmentation algorithm will not work.

Hi Image Analyst,

Thank you for your suggestion. I have just added the image to illustrate the applications.

Thank you!
