How can I track the upper corners of the bounding box.

I'm trying to track the hand region. As it seems suitable for me I want to track the upper corners of the bounding box in each frames. I've found the corners and marked it with blue.

Now, I want to track these corner points in each frame.

regionprops() will give you the bounding box.

measurements = regionprops(labeledImage, 'BoundingBox');

BoundingBox is a member/field of the measurements structure. See my Image Segmentation Tutorial if you need a demo: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

Yeah, I've found the bounding box. Now, I've to track the upper corners of the bounding box in each frame. Can you suggest any method to do the tracking.

Just log the (x,y) coordinates to an array or file each time you get a new set.

But do I need to use some specific tracking algorithm or can i just work with this coordinates for classification?
