Abstract
Various implementations disclosed herein include devices, systems, and methods that determines changes in depth category of pixels from one image to the next. For example, changes in depth category may include determining that a given pixel has changed from foreground to background or vice versa. The technique is based on creating a histogram or other model using a mask identifying a depth category of pixels in the first image. The histogram or model is used to assess a pixel in the first frame and the second frame and identify a change in its depth category. One use of this technique is to determine a change in occlusion.
