We present a new method for detecting incorrect feature point tracking. For 3-D reconstruction and motion segmentation, we track feature points through a video sequence, then remove outlier trajectories among them. If we detect image frames in which feature point tracking fails, we can correct incorrect trajectories and reuse them. In this paper, we detect incorrect feature point tracking by imposing the constraint that under the affine camera model feature trajectories should be in an affine space in the parameter space. Introducing a statistical model of image noise, we test the partial trajectories are sufficientlly reliable. Then we detect incorrect partial trajectories. Using real video images, we demonstrate that our proposed method sufficientlly detects incorrect feature point tracking. |
