Online Object Recognition by MSER Trajectories
This work presents a robust online learning and recognition system. The basic idea is to exploit information from tracking an object during the recognition and/or learning stage to obtain increased robustness and better recognition results. Object tracking by means of an extended MSER tracker is utilized to detect local features and construct their trajectories. Compact object representations are formed by summarizing the trajectories. All steps are performed online including the MSER detection, tracking, summarization, SIFT description as well as learning and recognition based on a vocabulary tree. The proposed method is evaluated on realistic video sequences which prove the increased performance for robust online recognition
