Hey Sir,
I am a certified computer vision expert and have six years of MATLAB experience. I have already done such tasks in brain tumor region of interest extraction and various other diseases region of interest extraction. I can do this via contours or coneected components using a threshold.
I can assure you that it can be done in one day and with efficient code that is felxible for multiple image and background sizes.
