This thesis proposes a robust on-line tracking method by 1) enlarging the convergence range and 2) improving the observation memory of a phase-based appearanceadaptive “Wandering Stable Lost” (WSL) tracker, which was developed by Jepson, Fleet and El-Maraghi. The resultant tracker is demonstrated to be adaptive to temporary and permanent appearance changes in the object being tracked while at t...
In this paper we present an efficient algorithm for tracking multiple players during indoor sports matches. A sports match can be considered as a semi-controlled environment for which a set of closed-world assumptions regarding the visual as well as the dynamical properties of the players and the court can be derived. These assumptions are then used in the context of particle filtering to arriv...
In this paper, we propose a robust vehicle tracker for Infrared (IR) videos motivated by the recent advance in compressive sensing (CS). The new eL1-PF tracker solves a sparse model representation of moving targets via L1 regularized least squares. The sparsemodel solution addresses real-world environmental challenges such as image noises and partial occlusions. To further improve tracking perf...
Although object tracking has been studied for decades, real-time tracking algorithms often suffer from low accuracy and poor robustness when confronted with difficult, realworld data. We present a tracker that combines 3D shape, color (when available), and motion cues to accurately track moving objects in real-time. Our tracker allocates computational effort based on the shape of the posterior ...
The Online Silicon Vertex Tracker is the new CDF-II level 2 trigger processor designed to reconstruct 2-D tracks within the Silicon Vertex Detector with high speed and accuracy. By performing a precise measurement of impact parameters the SVT allows tagging online B events which typically show displaced secondary vertices. Physics simulations show that this will greatly enhance the CDF-II B-phy...
