Abstract
Aspects of the present invention allow for real-time people monitoring method and system for estimation of the size and flow density of a given group of people located in a given area of space. The method and system may be used to monitor live or recorded camera input, foreground segmentation, human tracking, height estimation, and dwell estimation. In particular, human detection may be achieved using a spatio-temporal variance analysis calculation methodology for moving target detection.
