Can you attach the original image using the paperclip button for attachments, and provide code you used to generate the binary image to the right.

I resized the image 3 times and use bwboundaries to find its boundaries, then for the boundaries of the real image, I found the closest integer to points of the resized boundaries divided by 3.
