METHODS AND APPARATUS FOR IMPLICIT AND SEMI-IMPLICIT INTRA MODE SIGNALING FOR VIDEO ENCODERS AND DECODERS

摘要

Methods and apparatus are provided for implicit and semi-implicit intra mode signaling for video encoders and decoders. An apparatus includes an encoder for encoding picture data for at least a portion of a picture. The encoder derives an intra mode to apply to the portion from neighboring template data and abstains from explicitly signaling the intra mode for the portion. The neighboring template data corresponds to a neighboring template formed from neighboring pixels with respect to the portion.
