Abstract

We present a system that is capable of segmenting, detecting and tracking multiple people in a cluttered scene using multiple synchronized cam- eras located far from each other. The system improves upon existing systems in many ways including: (1) We do not assume that a foreground connected compo- nent belongs to only one object; rather, we segment the views taking into account color models for the objects and the background. This helps us to not only sep- arate foreground regions belonging to different objects, but to also obtain better background regions than traditional background subtraction methods (as it uses foreground color models in the algorithm). (2) It is fully automatic and does not require any manual input or initializations of any kind. (3) Instead of taking de- cisions about object detection and tracking from a single view or camera pair, we collect evidences from each pair and combine the evidence to obtain a decision in the end. This helps us to obtain much better detection and tracking as opposed to traditional systems.
