Abstract
Systems and methods are disclosed for coding pixel blocks of an input frame in which coding costs of a plurality of candidate coding modes are estimated. A coding cost of a candidate coding mode may be estimated based on noise estimate associated with the candidate coding mode. A coding mode for the input pixel block may be selected based on a comparison of the estimated coding costs of the plurality of candidate coding modes. The input pixel block may then be coded according to the selected coding mode.
