See attached photos for reference. What functionality does MATLAB have for detecting black space and zeroing in on what's inside that space?
Thanks for your help.

See attached M file for an example of one way to approach this problem. If you want to get a perfect oval, look at 'regionprops' to extract that sort of information from the binary image or the connected components structure ('cc').
