Particle Filtering with Region-based Matching for Tracking of Partially Occluded and Scaled Targets
Visual tracking of arbitrary targets in clutter is important for a wide range of military and civilian applications. We propose a general framework for the tracking of scaled and partially occluded targets, which do not necessarily have prominent features. The algorithm proposed in the present paper utilizes a modified normalized cross-correlation as the likelihood for a particle filter. The al...
متن کاملTracking Ground Based Targets in Aerial Video with Dual-Tree Complex Wavelet Polar Matching and Particle Filtering
The detection and tracking of targets in aerial imagery of cluttered urban environments is addressed. Polar matching, using dual-tree complex wavelet transforms, is used as a shift and rotation invariant detector. A particle filter is employed to add robustness, especially in the event of target occlusion. We show that, together, these methods can robustly track a ground based target as it beco...
متن کاملCombining Edge and Color Features for Tracking Partially Occluded Humans
We propose an efficient approach for tracking humans in presence of severe occlusions through a combination of edge and color features. We implement a part based tracking paradigm to localize, accurately, the head, torso and the legs of a human target in successive frames. The Non-parametric color probability density estimates of these parts of the target are used to track them independently us...
متن کاملSom Based Particle Matching for Volumetric Particle Tracking Velocimetry
Novel 3D image analysis and particle matching techniques for the use in the volumetric particle tracking velocimetry have been developed and tested by using synthetic images and experimental images of unsteady 3D flows. A tomography based particle reconstruction scheme along with the subsequent process of individual particle detection and validation was used. The detected particles in the two t...
متن کاملIntegrated detection and tracking of multiple faces using particle filtering and optical flow-based elastic matching
The design and implementation of a multiple face tracking framework that integrates face detection and face tracking is presented. Specifically, the incorporation of a novel proposal distribution and object shape model within the face tracking framework is proposed. A general solution that incorporates the most recent observation in the proposal distribution using a multiscale elastic matching-...
