Abstract
A computer-based system forms a more accurate intensity value for virtual light reflected from computer-generated images. The reflected light intensity from the images is computed pixel by pixel using the mean and variance of the depth values of a filter region associated with the pixel, as well as the maximum and minimum values of the depth values in the filter region. The computations use the normalized, incomplete beta function algorithm.
