MATLAB: How to trace the outline of an image with the mouse and return the coordiantes of the resulting shape

Question

I would like to be able to trace the outline of features in a image with the mouse and return the X Y coordinates of the resulting shape.

Answer 1

There is no single built in MATLAB function that will track the movement of the mouse on an open figure, draw the resulting curve and return its X Y coordinates. There are user submitted functions that will do this in MATLAB Central such as the MOUSETRACK function in the link below:
