Probabilistic Occupancy Map is a multi-camera human detection procedure, with its c++ implementation freely avaible at: http://cvlab.epfl.ch/software/pom

In order to utilize this handy piece of software one needs:

1. A series of synchronized video frames from multiple cameras after background removal procedure.
2. A configuration file for a particular scenario.

POM ships with an example set of video frames and related configuration file.

My problem can be stated as follows: Given a sequence of synchronized videos (for example from http://cvlab.epfl.ch/data/pom) how do I generate the configuration file required by POM? In particular I'm interested in the RECTANGLE tag of the configuration. The readme states:

RECTANGLE [camera number] [location number] notvisible|[xmin] [ymin] [xmax] [ymax]

Defines the parameters of a certain rectangle, standing for an individual at a certain location viewed from a certain camera. All non-specified rectangles are "not visible" by default.

From my understanding it defines how a person's bounding rectangle would look like at a certain location viewed from a certain camera. This has to be defined for every (grid) location for every camera (given the location is in the camera's Field of View - if not, notvisible is used or the rectangle may be left undefinied).

Doing this by hand is not impossible, but certainly is impractical. So, to sum up: How do I generate the POM configuration file if I have a set of videos from multiple cameras?
