| Abstract(in English) | Segmentation of dynamic scene using optical flow is an important research field in image recognition. However the estimation of the optical flow is sensitive to noise, many conventional methods are required to segment the image iteratively by using clustering algorithm. In contrast to this approach, simultaneous and direct estimation of multiple attribute in the image is possible by means of principle of superposition. In this paper, we propose a new method that simultaneously estimate a set of affine parameters of moving regions in dynamic image based on principle of superposition. We also propose noise reduction technique using spatio-temporal BPF to reduce aliasing in input data. Experimental result from real image sequence shows the effectiveness of the proposed method. |
