NON-LINEAR RATE-DISTORTION OPTIMIZATION IN VIDEO COMPRESSION PROCESS

Abstract: systems and methods herein are for a video encoder to be associated with a rate optimization distortion (rdo) module and a calibration module, where the rdo module may be to perform rdo for received frames of a media stream and may be to generate at least an rdo output that is based in part on quality measures between the received frames and decoded frames, and where the calibration module may be to provide an evaluation metric that is to scale or transform at least a range of the quality measures, with the scaling or transforming to potentially reduce an effect on a compression performed in the video encoder.
