Abstract
A technique for processing video includes receiving a pixel array, such as a block or layer of video content, as well as a mask that distinguishes masked, 'don't-care' pixels in the pixel array from unmasked, 'care' pixels. The technique encodes the pixel array by taking into consideration the care pixels only, without regard for the don't-care pixels. An encoder operating in this manner can produce a simplified encoding of the pixel array, which represents the care pixels to any desired level of precision, without regard for errors in the don't-care pixels, which are irrelevant to reconstruction. Further embodiments apply a polynomial transform in place of a frequency transform for encoding partially-masked video content, and/or video content meeting other suitable criteria.
