Hi there, I am interested in specifiying a region of interest in an image, with a specified area A. A possibility is maybe to modify the roipoly function, but I don't know how to do it quickly.
I am quite new and I don't know if in matlab there are similar functionalities...
Thanks to all
Alessio

Well, yes you'll probably have to write some code. But you can easily and quickly generate masks of a non-convex area with poly2mask, and then sum it or use bwarea to get its area, and then dilate it or erode it automatically if too big or too small.
