To enhance the efficiency and accuracy of Kalman filter computations, in particular the time and measurement updates, UDU factorization is employed. An interesting feature of the current implementation is the extension to semi-positive (nonnegative) matrices and systems with a time-varying state...

Filtering the image using a simple mask will give a large response at the transition from background to finger. These large responses are located and used as detected finger edge. The function will return the location of these edges and will return a binary mask indicating the finger region.Note...
