How to find the nearnest object to a clicked point in a binary image?

3 views (last 30 days)
Dear all,
I have a binary image that has two sperated white pixel A and B = 1 and far from each other.
If I use [x_cordinate, y_cordinate] = ginput(1) and clicked somewhere in the image, then is there some way to know which of the points A or B is the closest to the clicked pixel?
Any help will be appreciated.

If they're just a single pixel, and you know their coordinates, just use the Pythagorean theorem. You can use sqrt() or hypot() - your choice.
If they not just a single pixel, but an extended blob, then first read this and then let me know.
