    摘要: There are provided methods and apparatus for fast geometric mode decision in a video encoder. An apparatus includes an encoder (100) for performing a non-exhaustive geometric mode decision using geometric model-based partitioning modes. The encoder (100) skips a testing of the geometric model-based partitioning modes based on at least one of a correlation and a dependence between the geometric model-based partitioning modes and non-geometric partitioning modes.

    摘要: There are provided a method and apparatus for reusing available motion information as a motion estimation predictor for video encoding. The apparatus includes an encoder for encoding an image block by determining a motion estimation predictor for the image block using motion information previously generated from an element other than the encoder, and using the motion estimation predictor in a motion estimation process to generate a motion vector for the image block. The motion estimation predictor is used in place of at least one predictor otherwise used in the motion estimation process. The at least one predictor is any of a search window predictor, a temporal predictor, and a block type predictor.

    摘要: There are provided video encoders and corresponding methods for encoding video data for an image that is divisible into macroblocks. A video encoder includes an encoder for performing inta mode selection when encoding a current macroblock by testing a first subset of intra modes to compute a rate distortion cost, and utilizing the rate distortion cost to determine whether to terminate the intra mode selection and which additional intra modes, if any, are to be examined with respect to the current macroblock.

    摘要: A method and apparatus are provided for detecting image blocking artifacts. The apparatus includes a full-reference blocking artifact detector for detecting blocking artifacts in a processed version of a picture based on a blockiness metric. The blockiness metric is determined based on respective local variations in the processed version of the picture and in an original version of the picture.

    摘要: Methods and apparatus are provided for video image pruning. An apparatus includes a data pruner for pre-processing a picture prior to, and in preparation for, compression by encoding. The data pruner selectively removes, in the spatial domain, at least one region within the picture. At the decoder end, an apparatus includes a data restorer for receiving a decompressed picture subsequent to decompression by decoding, and post-processing the decompressed picture by selectively restoring, in the spatial domain, at least one region in the decompressed picture based on information indicating a removal of the at least one region prior to a previously performed encoding process.
