摘要： An encoder configured to encode a video bitstream for decoding by a compliant decoder configured to receive the bitstream, the encoded bitstream including a reference picture and a current picture including a coded current block, the bitstream also including an index useful for determining a scaling factor. The decoder determines that a mode when a reference picture and a current picture have different resolutions is enabled. Utilizing the mode, the decoder reconstructs the coded current block encoded by the encoder by determining a scaling factor using information in the bitstream including the index, determining a scaled prediction block by scaling a block of the reference picture using the scaling factor and by applying a pixel interpolation filter determined specifically for the prediction block and combining the scaled prediction block with a residual.

摘要： Systems and methods for event and object detection and annotation in the video streams may include extracting a plurality of features in a picture in a video frame, grouping at least a portion of the plurality of features into at least one object, determining a region for the at least one object, assigning object identifiers to the at least one object and encoding the object identifiers into the bitstream. Feature-based rate distortion optimization may be employed for video coding including extracting a set of features from a picture in the video, generating a relevance map for the extracted features, determining a relevance score for portions of the picture using the relevance map, and encoding the portion of the picture with a bit rate determined at least in part by the relevance score.

摘要： A video encoder s configured to encode a bitstream to be decoded by a compatible decoder, the bitstream including a coded picture with a first region with a first contiguous plurality of coded blocks and signaling information associated with each coded block. For each coded block in the first region, in response to the associated signaling information, the decoder receiving the bitstream constructs a motion vector candidate list including a motion vector candidate enabling the reconstruction of global motion in the first region. If the motion vector candidate is a translational motion vector, the decoder decodes the blocks in the first region using translational motion compensation to reconstruct global motion in the first region. If the one motion vector candidate comprises multiple control point motion vectors, the decoder uses affine motion compensation to reconstruct global motion in the first region.

摘要： An encoder configured to generate an encoded bitstream for decoding by a compatible decoder, wherein the decoder receives the encoded bitstream with a current picture including a current block having a first partition boundary partitioning the block into first and second non-rectangular regions and a second partition boundary, intersecting the first partition boundary, and partitioning the second non-rectangular region into three portions. Using the encoded bitstream, the decoder determines a first predictor for use within the first non-rectangular region using a first motion vector selected from a first list of motion vector candidates, determines a second predictor for use within the second non-rectangular region using a second motion vector selected from a second list of motion vector candidates; and decodes the current block using the first predictor and the second predictor. Decoding further includes smoothing the first predictor and the second predictor across the first partition boundary.
