drawing on the image - swamigmv - Sep 17 7:52:42 2007

hi all
i am doing a project on image segmentation where i have to specify the 
area to be segmented(not exactly but a rough scketch)
now how can i get that sketch i draw on the image.i.e. the set of 
pixels that i mark?
(or)
is there any way to scribble on a image and get those scribbles as 
inputs?

Try using the function "roipoly" in the matlab image processing tool box.
