Multiple camera control system
First Claim
1. A computer-implemented method comprising:
- accessing, by a processor, a first image of a scene and a second image of the scene, wherein the first image comprises a first view of the scene and the second image comprises a second view of the scene;
analyzing, by the processor, the first image and the second image to detect an object of interest in at least one of the first image and the second image;
determining, by the processor, three-dimensional coordinates representing a location of the detected object of interest;
generating, by the processor, a history comprising the determined three-dimensional coordinates of the object of interest;
detecting, by the processor, an occurrence of a gesture made by the object of interest by analyzing the history of three-dimensional coordinates; and
controlling, by the processor, an electronic application based on detecting the occurrence of the gesture.

Abstract
A multiple camera tracking system for interfacing with an application program running on a computer is provided. The tracking system includes two or more video cameras arranged to provide different viewpoints of a region of interest, and are operable to produce a series of video images. A processor is operable to receive the series of video images and detect objects appearing in the region of interest. The processor executes a process to generate a background data set from the video images, generate an image data set for each received video image, compare each image data set to the background data set to produce a difference map for each image data set, detect a relative position of an object of interest within each difference map, and produce an absolute position of the object of interest from the relative positions of the object of interest and map the absolute position to a position indicator associated with the application program.
