I need to draw a polygon shape boundary over the image and access all the coordinate points inside the boundary-
Please help me to draw the arbitary shape boundry over an image and store all the coordinates of [x y] in a variable.
Thanks in advance.

You can use poly2mask() and bwboundaries(). It will get the boundaries of any blobs, whether exterior or interior (holes of the donut).
