A method and system for processing captured image information in an interactive video display system. In one embodiment, a special learning condition of a captured camera image is detected. The captured camera image is compared to a normal background model image and to a second background model image, wherein the second background model is learned at a faster rate than the normal background model. A vision image is generated based on the comparisons. In another embodiment, an object in the captured image information that does not move for a predetermined time period is detected. A burn-in image comprising the object is generated, wherein the burn-in image is operable to allow a vision system of the interactive video display system to classify the object as background.

What is claimed is: 1. A method for adapting to changes in captured camera images in an interactive video display system, the method comprising: developing a slow-changing background model and a fast-changing background model, each of the background models based in part on trends in the captured camera images, the models developed at a computing device; detecting a background change in one or more of the captured camera images with respect to the slow-changing background model, the background changed captured by a camera; determining that the background change exceeds a threshold associated with the slow-changing background model, the determination made by the computing device; and generating a vision image using the fast-changing background model as a result of the background change exceeding the threshold, the vision image rendered on a video display. 2. The method of claim 1, wherein the threshold includes a percentage of the camera image being obscured for a specified period of time. 3. The method of claim 1, wherein the threshold includes a specified portion of the pixels in the camera image having a value that exceeds a particular threshold for a particular length of time. 4. The method of claim 1, further comprising: replacing the slow-changing background model with the fast-changing background model; and developing a new fast-changing background model to replace the old fast-changing background model. 5. The method of claim 4, wherein the slow-changing background model is replaced with the fast-changing background model once the background change no longer exceeds the threshold. 6. The method of claim 1, further comprising generating a further vision image using the slow-changing background model as a result of the background change no longer exceeding the threshold, the further video image rendered on the video display. 7. The method of claim 6, wherein the threshold includes a percentage of the camera image no longer being obscured for a specified period of time. 8. The method of claim 6, wherein the threshold includes a specified portion of the pixels in the camera image having a value that no longer exceed a particular threshold for a particular length of time. 9. The method of claim 6, wherein the threshold includes a subset of the camera image staying constant for a specified period of time. 10. An interactive display system, the system comprising: a camera configured to capture images; a computing device configured to: developed a slow-changing background model and a fast-changing background model, each of the background models based in part on tends in the images captured from the camera, detect a background change in one or more of the images captured from the camera with respect to the slow-changing background model, and determine that the background change exceeds a threshold associated with the slow-changing background model; and a video display configured to display a vision image generated using the fast-changing background model in response to background change exceeding the threshold. 11. The interactive display system of claim 10, wherein the threshold includes a percentage of the camera image being obscured for a specified period of time. 12. The interactive display system of claim 10, wherein the threshold includes a specified portion of the pixels in the camera image having a value that exceeds a particular threshold for a particular length of time. 13. The interactive display system of claim 10, wherein the computing device is further configured to replace the slow-changing background model with the fast-changing background model; and develop a new fast-changing background model to replace the old fast-changing background model. 14. The interactive display system of claim 13, wherein the slow-changing background model is replaced with the fast-changing background model once the background change no longer exceeds the threshold. 15. The interactive display system of claim 10, wherein a further vision image is generated using the slow-changing background model as a result of the background change no longer exceeding the threshold, the further video image rendered on the video display. 16. The interactive display system of claim 15, wherein the threshold includes a percentage of the camera image no longer being obscured for a specified period of time. 17. The interactive display system of claim 15, wherein the threshold includes a specified portion of the pixels in the camera image having a value that no longer exceed a particular threshold for a particular length of time. 18. The interactive display system of claim 15, wherein the threshold includes a subset of the camera image staying constant for a specified period of time. 19. A computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for adapting to changes in captured camera images, the method comprising: developing a slow-changing background model and a fast-changing background model, each of the background models based in part on trends in the captured camera images; detecting a background change in one or more of the captured camera images with respect to the slow-changing background mode; determining that the background change exceeds a threshold associated with the slow-changing background model; and generating a vision image using the fast-changing background model as a result of the background change exceeding the threshold.
