Method and system for processing captured image information in an interactive video display system

An interactive display system comprising:

• means for capturing images;
• means for generating a slow-changing background model based in part on trends in one or more captured images;
• means for generating a fast-changing background model based in part on trends in one or more captured images;
• means for detecting one or more changes in a background of one or more of the captured images used in generating the slow-changing background model;
• means for determining if the detected one or more changes exceed a threshold;
• and
• means for displaying vision images generated using the fast-changing background model in response to determining that the detected one or more changes the threshold.

An interactive display system, the system comprising:

• a camera interface configured to receive captured images from one or more cameras;
• a computing device configured to:
• develop a slow-changing background model and a fast-changing background model, each of the background models based in part on trends in the captured images received from the camera;
• detect a background change in one or more of the captured images with respect to the slow-changing background model;
• and
• initiate display of a vision image generated using the fast-changing background model on a video display in response to determining that the detected background change exceeds a threshold;
• and
• a video interface configured to be coupled to a video display device.

A method for determining if one or more objects in an image are burned-in, the method comprising:

• storing a burn-in image in a computer readable memory;
• receiving a plurality of images from a camera device;
• determining that a first object has remained substantially fixed in a foreground of the plurality of images for at least a first predetermined period of time;
• and
• adding the first object to the burn-in image.

An imaging system for determining if one or more objects in a series of images are burned in, the system comprising:

• an interface configured to receive images from one or more imaging devices;
• one or more storage devices configured to store a burn-in image and a background image;
• and
• a processor configured to
• detect a first object in one or more of the images that remains substantially stationary in a foreground of the one or more of the images for at least a first predetermined time period;
• and
• classify one or more pixels associated with the first object as burned-in pixels, wherein the burned-in pixels collectively comprise the burn-in image.

A method for adapting a background in an interactive video display, the method comprising:

• generating a first background model and a second background model, each of the background models based in part on trends in a plurality of images received from one or more cameras;
• determining a background change in one or more of the plurality of images relative to the first background model;
• and
• initiating display of an output image generated using the second background model on a video display in response to determining that the detected background change exceeds a threshold.
