How can I average the boundaries of two separate binary images?
Show older comments
Input: I have two separate black&white (binary) images, each with two separate boundaries that are free-hand drawn (see attached images).
Aim: I would like to average the left boundary/trace in the two images as well as the right boundary, so that I would eventually have an average mask that is the average of those two images.
Process: (1) Initially, I thought that I can do this by averaging the elements of the matrices, but that didn't work because some of the averaged matrix elements became fractions, such as 1/2. (2) I also thought that if a reference point is selected and the coordinates of each of those boundaries are known, then I should be able to determine the average of the two boundaries in the two images, but I don't know exactly how to do that, and I am not sure if that's a correct approach.

What is your definition of the average of two shapes?
