Abstract
Embodiments of the invention include systems and methods for automatically detecting persons and/or other objects in a video signal. Automatic color compensation is applied to the video signal based on measured color of a reference area of the video signal. Generally the reference area is an area of the video signal that does not change often over time. The color compensated video signal is then analyzed for the appearance of objects and persons. In some instances the persons are identified using facial or other type of recognition. Counters or other trackers may provide real-time information, such as how many people are currently on a particular floor of a building.
