Detailed Description

Demo code to calculate moments.

Demo code for detecting corners using Shi-Tomasi method.

Demo code to obtain ellipses and rotated rectangles that contain detected contours.

Demo code for detecting corners using Harris-Stephens method.

Demo code to find contours in an image.

This is a demo of adding image (linear blending).

This is a demo that shows mean-shift based tracking You select a color objects such as your face and it tracks it. This reads from video camera (0 by default, or the camera number the user enters
