[Other] Tracking-of-Small-Targets- DL : 0: An effective approach to the detection and tracking of small moving targets with low contrast is proposed-The detection and tracking of small moving targets in low signal-to-noise ratio and cluttered environments is a very important problem in surveillance and target tracking [l]. In the past two decades, extensive research has been carried out to solve the problem, including Kalman filter, probabilistic data association, multiple hypothesis testing 121 and etc.

[Other] kernel_based_object_tracking_survey DL : 0: A new approach toward target representation and localization, the central component in visual tracking of nonrigid objects, is proposed. The feature histogram-based target representations are regularized by spatial masking with an isotropic kernel. The masking induces spatially-smooth similarity functions suitable for gradient-based optimization, hence, the target localization problem can be formulated using the basin of attraction of the local maxima. We employ a metric derived from the Bhattacharyya coefficient as similarity measure, and use the mean shift procedure to perform the optimization. In the presented tracking examples, the new method successfully coped with camera motion, partial occlusions, clutter, and target scale variations. Integration with motion filters and data association techniques is also discussed. We describe only a few of the potential applications: exploitation of background information, Kalman tracking using motion models, and face tracking.
