ı found a kalman tutorial from http://opencvexamples.blogspot.com/20... when ı build this codes, VS 2012 gives me error C2100: illegal indirection about line which includes KF.transitionMatrix = *(Mat_<float>(4, 4) << 1,0,1,0, 0,1,0,1, 0,0,1,0, 0,0,0,1); what can ı do to vanish this error?

That piece of code is just plain incorrect because you are adding a pointer to a smart pointer, which is unusual in C++. Not sure why the pointer should be there.

KF.transitionMatrix = *(Mat_<float>(4, 4) << 1,0,1,0, 0,1,0,1, 0,0,1,0, 0,0,0,1);

should at least be

KF.transitionMatrix = (Mat_<float>(4, 4) << 1,0,1,0, 0,1,0,1, 0,0,1,0, 0,0,0,1);

as you can see in the official Kalman filter example!
