| Abstract(in English) | The factorization method for the structure-from-motion is stable in calculation and gives an accurate reconstruction from a tracking result which contains only a single object, however, it is affected by the outliers such as false tracking and other objects because of using the least squares criterion. Then we present a robust factorization method for GAP(generalized affine projection)model. Using the LMedS(Least Median of Squares)criterion, we can discard feature points which is regarded as outliers, then a measurement matrix is stably decomposed into the motion and shape matrices in the first stage of the factorization method. We revise this method into the iterative factorization method for real time processing. Some experiments using synthetic data and a real sequence are given to show the performance of our proposed robust factorization method. |
