Get contours of a Hand painted at ones in Android

asked 2013-11-11 10:11:59 -0500

I am a beginner ,

I want to draw something and get its contours without writing it into a img file ,on the screen of a Android phone,

almost all examples show that getting contours using cvfindcontours from a jpeg file or png and so on,

if anyone can show me some codes about convent drawings to mat format ? Thanks a lot.

do you mean : contours of something you want to draw ? (as opposed of : contours in a photo/image)
