CrossTrackingUsingKLT.m

Hi,

I use KLT algorithm for tracking on video file and using "estimateGeometricTransform" function I would like to estimate the transform matrix. The tracking is carried out fine but I tried, without success, to restore the frames with the movements using this transform matrix and a "Affine" transform, so eventually the frames will be displayed as it was initially in the first frame - motionless. can you help me to use the "estimateGeometricTransform" function and "Affine" transform correctly? I used in the example "FaceTrackingUsingKLTExample" from your wensite (<http://www.mathworks.com/help/vision/examples/face-detection-and-tracking-using-the-klt-algorithm.html#vision_product-FaceTrackingUsingKLTExample> ) but I change only the object after him the tracking is performed (I tracks after a cross in the video file, not after a face) the code is attached.

Thanks, Itai
