KL_Tracker

class KL_Tracker extends Tracker

The KL_Tracker class is used for image tracking based on the idea of minimizing the difference between a sub-image of 'a' subsequent displaced sub-image of 'b'.

    Find an optimal displacement vector 'd', so that point 'u' in image 'a' matches point 'v = u + d' in image 'b', returning vector 'd' and its error 'e'. Solve for 'd' in the following system of equations.

    Z d = df

    where 'Z' is the gradient outer product matrix, 'd' is the displacement

    u

    the point in image 'a' for which a matching point 'v' is to found in 'b'
