This paper presents a novel approach to stabilize digital video sequences. A 2.5D inter-frame motion model is proposed so that the stabilization system can perform in the situations where significant depth changes are present and the camera has both rotation and translation. Inertial motion filtering is proposed in order to eliminate the vibration of the video sequences with enhanced perceptual properties...
LoG filters have been widely used as a second derivative filtering function. One problem with LoG filtering is that it is very time consuming, especially with a large size filter. We use an analytical method to obtain the z-transform of LoG function in a rational function form and develop a recursive implementation. The structure of the recursive filters is defined by the order of rational functions...
