摘要：In this paper, we propose a 2D feature tracking method that is stable to long video sequences. To improve the stability of long track- ing, we use trajectory information about 2D features. We predict the expected feature states and compute a rough estimate of the feature lo- cation on the current image frame using the history of previous feature states up to the current frame. A search window is positioned at the esti- mated location and similarity measures are computed within the search window. Once the feature position is determined from the similarity mea- sures, the current feature states are appended to the history bu®er. The outlier rejection stage is also introduced to reduce false matches. Ex- perimental results from real video sequences showed that the proposed method stably tracks point features for long frame sequences.
