Abstract:
Real-time, hardware-implementable Structured Similarity (SSIM)-based rate distortion optimization (RDO) techniques for video transmission are described. The disclosed techniques provide efficient application of SSIM as a distortion metric in selecting prediction modes for encoding video for transmission. A prediction mode, at a high level, specifies which previously encoded group of pixels can be utilized to encode a subsequent block of pixels in a video frame. A less compute intensive distortion metric is first used to select a subset of candidate prediction modes. Then a more compute intensive SSIM-based selection is made on the subset. By utilizing the disclosed techniques during video encoding, tradeoffs between distortion and transmission rate can be made that are more relevant to human perception.

Claim (Index 21):
A non-transitory computer readable storage medium having instructions stored thereon that, when executed by processing circuitry, causes the processing circuitry to performing operations comprising:\n calculating, using a first type of distortion estimation on a block of pixels from a frame of input video, first distortion values for a first plurality of prediction modes; selecting, based at least on the first distortion values, a second plurality of prediction modes, wherein the second plurality is a subset of the first plurality of prediction modes; calculating, using structured similarity (SSIM) distortion estimation on the block, second distortion values for each prediction mode in the second plurality of prediction modes; identifying, based on the second distortion values and bit rates for encoding the block according to respective ones of the second plurality of prediction modes, a prediction mode for encoding the block; and encoding the block using the identified prediction mode.
