Content adaptive motion compensated precision prediction for next generation video coding
Abstract:
Techniques related to adaptive precision and filtering motion compensation for video coding may include, for example, determining, via a motion compensated filtering predictor module, a motion compensation prediction precision associated with at least a portion of a current picture being decoded, where the motion compensation prediction precision comprises at least one of a quarter pel precision or an eighth pel precision. Predicted pixel data of a predicted partition associated with a prediction partition of the current picture may be generated, via the motion compensated filtering predictor module, by filtering a portion of a decoded reference picture based at least in part on the motion compensation prediction precision. Prediction partitioning indicators associated with the prediction partition and a motion vector indicating a positional difference between the prediction partition and an associated partition of the decoded reference picture may be coded, via an entropy encoder, into a bitstream.
