Draw freehand a contour in alternate blue/yellow color to be visible on top of various pictures and get a set of X,Y coordinates of all the contour pixels
requires to open figure first and put "hold on"
I am new to matlab. one request to the author: please provide demo or example file.
@bibek dash : I can not draw "anything".
@ All: I click and drag to write something but all it shows is a polygon. What to do to write "N" in the figure.
extremely useful elegant piece
It is very good.
A few "nits":
In the help for the function, it implies a non-existant argument, x,which should be cleaned up.
Also, I personally dislike the "convhull" that redoes what is drawn "freehand" ; I removed it, but this wasn't completely trivial.
None-the-less, a really, really, great GUI file!
These comments are my own and not my organization's.
