Abstract:
A method for evaluating region cluster image information obtained from a scene to determine whether the region cluster represents an object to be tracked, the method comprising steps of:generating at least one real-world feature for each region cluster that represents a characteristic of the region cluster in a real-world space comprising steps of: (i) determining at least one possible location of a predetermined portion of the region cluster based on a viewing angle of the scene by a video camera which views the scene: (ii) determining a distance from the video camera to the object corresponding to the region cluster in real-world coordinates for each possible location of the predetermined portion determined for the region cluster; and (iii) generating real-world size and location information for the region cluster based on the distance; andcomparing the real-world size and location information for the region cluster with statistical information to generate a confidence value for each region cluster that represents a likelihood that the region cluster represents an object to be tracked.
