Real Time Moving Object Tracking by Particle Filter

Robust and Real time moving object tracking is a tricky job in computer vision problems. Particle filtering has been proven very successful for nongaussian and non-linear estimation problems. In this paper, we first try to develop a color based particle filter. In this approach, the object tracking system relies on the deterministic search of window, whose color content matches a reference histogram model. A simple HSV histogram-based color model is used to develop our observation system. Secondly and finally, we describe a new approach for moving object tracking with particle filter by shape information. The shape similarity between a template and estimated regions in the video scene is measured by their normalized cross-correlation of distance transformed image. Our observation system of particle filter is based on shape from distance transformed edge features. Template is created instantly by,selecting any object from the video scene by a rectangle. Experimental results have been presented to show the effectiveness of our proposed system.
