| Abstract(in English) | Many of approaches to estimate velocity field (optical flow) from sequential images have been proposed since 70's. The gradient-based method and the correlation-based method are typically used. We use both of them by interpolating quadratic surfaces of intensity in the vicinity of each pixel on successive frames. Under the rigidness assumption, we can match the brightness and its gradient distribution of a local region on each frame, and then the local velocity vector can be obtained. Experimental results shown here are comfirmed the performance of presented method for several synthetic and real images. |
