A People Counter Using Top-view Video Sequences

[[abstract]]In this thesis, we propose a bi-directional people counting system based on top-view video sequences. The system is divided into two sub-systems: people detection and people tracking. For people detection, we extract foreground object by two features of object: attention region and the boundary between objects and background. The attention region is generated by motion detection. Since people may stay at same location, our system should consider the stopping objects into attention region. Then we can use level set method to extract the objects. For people counting, we use particle filter to tracking objects to solve object merge-split problem. Each particle is represented by an ellipse. One object is tracking by a set of particles. The likelihood function of the particle weight is defined by location, color, and shape style. Using expect state to be output of our system. Then we use the tracking result to count number of people. Our system has been tested in different lighting conditions (e.g. weather, time, and environment) and using video sequences catching from different camera types (e.g. ordinary, and fish eye cameras) to show the robust of system.
