| Research Abstract |
In order to generate a background panoramic image from a video stream, we proposed a new method for detecting mistracking points from tracked feature points in the video stream. We already proposed a mistrackiong points detection method. In this method, we robustly fit an affine space to feature point trajectories, and detect mistracking points by computing the distance from the fitted affine space. We developed this method to be able to detect mistracking points even if multiple moving objects exist in a video stream. Moreover, in order to estimate bakground colors in the background panoramic image generation, we proposed a clastering method based on an EM algorithm. We also proposed a method for generating a trimap from the extracted initial foreground regoins.
