We present a novel framework for multiple pedestrian tracking using overlapping cameras in which the problems of object detection and data association are solved alternately. In each round of our algorithm. the people are detected by inference on a factor graph model at each time slice. The outputs of the inference. https://www.roneverhart.com/HP-Pavilion-15-eg2373cl-15-6-FHD-Touch-Laptop-Intel-Core-i7-1255U-3-50-GHz-GeForce-MX550-16GB-DDR4-512GB-SSD-Windows--p8309/
