Shape Tracking Question

Hi,

I'm a C programmer with a background in multimedia programming (mainly audio, but some image processing and OpenGL). I have no background in CV so I'm not even sure if what I'm asking below is possible or whether OpenCV has the right tools to do it.

For my own interest I'm developing an application that tracks storm clouds. My input data is a series of .png images each representing a radar scan about five minutes apart. In most cases the clouds remain fairly similar from image to image although they can of course, split, grow, increase, etc. What I'd like to be able to do is track the cloud movement so that I can use the previous path to predict the future position of the storm cloud.

Is that something that OpenCV can be used for? If so, where should I begin?

Any help or suggestions would be appreciated.

Cheers,

Chris

For tracking, you can use VISP

However it is limited to rigid objects. For objects that can change shape, you can try the active contours functions in opencv :

Take a look at this thread

Hope this helps,
