You could simply used the mouse callback to draw points in your image. See the doc here. You could draw lines, points (circle), rectangles or polygons. See the doc of all these functions.
By the way, I don't think OpenCV is the best approach for that kind of application.
Thanks a lot for replying, i got to know that the OpenCV is not for developing that type of applications. So, can you suggest me some beginner assignment to me? I appreciate you .
Actually, it depends on what you want. If you want to extract peoples hand with a webcam, then use their fingertips for example to create a drawing tool, then this is exact what you need. I am actually looking at your question from another perspective then Mathieu.
