Abstract :
This paper presents two advancements in motion estimation based on the 3-D Gabor representation. First, we introduce a new searching strategy and solve the estimation bias problem encountered in the current approach to piecewise translational motion estimation; second, in order to achieve better spatiotemporal resolution, we constructed a new algorithm that can provide dense motion field estimation.
