    ABSTRACT: We present a new object tracking scheme by employing adaptive classifiers to match the corresponding keypoints between consecutive frames. The detection of interest points is a critical step in obtaining robust local descriptions. This paper proposes an efficient feature detector based on SURF, by incrementally predicting the search space, to enhance the repeatability of the tracked interest points. Instead of computing the SURF descriptor, we construct a classifier-based descriptor using on-line boosting. With on-line learning ability based on our sample weighting mechanism, the classifier maintains its discriminative power to establish robust feature description and reliable points matching for subsequent tracking. In addition, matching candidates are validated using improved RANSAC to ensure correct updates and accurate tracking. All of these ingredients contribute measurably to improving overall tracking performance. Experimental results demonstrate the robustness and accuracy of our proposed technique.

    ABSTRACT: This paper introduces a topology based affine invariant descriptor for maximally stable extremal regions (MSERs). The popular SIFT descriptor computes the texture information on a grey-scale patch. Instead our descriptor use only the topology and geometric information among MSERs so that features can be rapidly matched regardless of the texture in the image patch. Based on the ellipses fitting for the detected MSERs, geometric affine invariants between ellipses pair are extracted as the descriptors. Finally topology based voting selector is designed to achieve the best correspondences. Experiment shows that our descriptor is not only computational faster than SIFT descriptor, but also has better performance on wide angle of view and nonlinear illumination change. In addition, our descriptor shows a good result on multi sensor images registration.

    ABSTRACT: Object tracking is a major technique in image processing and computer vision. In this paper, we propose a new robust feature-based tracking scheme by employing adaptive classifiers to match the detected keypoints in consecutive frames. The novelty of this paper is that the design of online boosting is combined with the invariance of local features so that the classifier-based descriptions are formed in association with the scale and rotation information. Furthermore, we introduce a sample weighting mechanism in the on-line classifier updating, for the subsequent tracking. Experimental results demonstrate the robustness and accuracy of our proposed technique.

    ABSTRACT: Image sequence registration has attracted increasing attention due to its significance in image processing and computer vision. In this paper, we put forward a new kernel based image registration approach, combining both feature-based and intensity-based methods. The proposed algorithm consists of two steps. The first step utilizes feature points to roughly estimate a motion parameter between successive frames; the second step applies our kernel based idea to align all the frames to the reference frame (typically the first frame). Experimental results using both synthetic and real image sequences demonstrate that our approach can automatically register all the image frames and be robust against illumination change, occlusion and image noise.
