Abstract
An exemplary method for estimating pixel values of displayed images captured by an image capture device comprises determining a status of a pixel of a displayed image based on a confidence value for the pixel and a comparison of an estimated value and a direct sampling value of the pixel, determining whether the pixel is obstructed based at least in part on the status and the confidence value, determining whether to update a pixel value of the pixel based at least in part on the status and whether the pixel is obstructed, repeating the determining steps for other pixels of the displayed image.
