| Abstract(in English) | In this paper, we propose a method of estimating global/local motion of affine parameters, which requires so little computational cost that its real-time implementation can be achieved. This method firstly tries to estimate the global motion of an image sequence by using pixel-wise matching scheme to verify motion vectors.Each motion vectors are generated based on random or spatio-temporal gradient of brightness.Then the method estimates affine parameters from the verified vectors by M-estimation. Secondly it compensates the estimated global motion and then extracts the pixels with large prediction error. The method similarly estimates the local motion parameters on the pixels. It repeats the local motion estimation until all local motion are compensated.We implement the method on a general PC and apply it on real image sequences. As a result, it proves to be effective and able to achieve real-time computation. |
