Abstract
A processing system selectively renders pixels or blocks of pixels of an image and leaves some pixels or blocks of pixels unrendered to conserve resources. The processing system generates a motion vector field to identify regions of an image having moving areas. The processing system uses a rendering processor to identify as regions of interest those units having little to no motion, based on the motion vector field, and a large amount of edge activity, and to minimize the probability of unrendered pixels, or “holes”, in these regions. To avoid noticeable patterns, the rendering processor applies a probability map to determine the possible locations of holes, assigning to each unit a probability indicating the percentage of pixels within the unit that will be holes, and assigning a lower probability to units identified as regions of interest.
