Hello, I have a binary image, and I would like to find x and y values of the most furthest point ---> so the point which is closest to border.

How can I do that?

Thank you

You can find all xy points in the binary image using

[y, x] = find(binaryImage);

You can find perimeter points with bwboundaries or bwperim

[y, x] = find(bwperim(binaryImage));

The point which is closest to the border of the blob is a point on the perimeter.

To find which point in the blob is closest to the border of the image, use bwdist

If you still need help, then explain better what you want in your reply, since now it's ambiguous.
