In this paper, the authors propose a 2D feature tracking method that is stable to long video sequences. To improve the stability of long tracking, they use trajectory information about 2D features. They predict the expected feature states and compute a rough estimate of the feature location on the current image frame using the history of previous feature states up to the current frame. A search window is positioned at the estimated location and similarity measures are computed within the search window.
