Hi All, I am trying to fill the following binary image to make it into a circle (not a perfect circle though, so trying to make into a circle using the centroid and max diameter provides results which are off a bit). The fact that it is at the edge of the binary object makes it challenging. Any pointers would be extremely useful. Thanks!

Not challenging at all since there's a function in the Image Processing Toolbox that will do that. Get the binary image, then call bwconvhull().
