摘要： A method decodes blocks in pictures of a video in an encoded bitstream by storing previously decoded blocks in a buffer. The previously decoded blocks are displaced less than a predetermined range relative to a current block being decoded. Cached blocks are maintained in a cache. The cached blocks include a set of best matching previously decoded blocks that are displaced greater than the predetermined range relative to the current block. The bitstream is parsed to obtain a prediction indicator that determines whether the current block is predicted from the previously decoded blocks in the buffer or the cached blocks in the cache. Based on the prediction indicator, a prediction residual block is generated, and in a summation process, the prediction residual block is added to a reconstructed residual block to form a decoded block as output.

摘要： A bitstream corresponding to an encoded video is decoded. The encoded video includes a sequence of frames, and each frame is partitioned into encoded blocks. For each encoded block, an edge mode index is decoded based on an edge mode codeword and a prediction mode. The edge mode index indicates a subset of predetermined partitions selected from a partition library according to the prediction mode. The encoded block is partitioned based on the edge mode index to produce two or more block partitions. To each block partition, a coefficient rearrangement, an inverse transform and an inverse quantization is applied to produce a processed block partition. The processed block partitions are then combined into a decoded block for a video.

摘要： A method reconstructs a depth image encoded as a base layer bitstream, and a set of enhancement layer bitstreams. The base layer bitstream is decoded to produce pixels of a reconstructed base layer image corresponding to the depth image. Each enhancement layer bitstream is decoded in a low to high order to produces a reconstructed residual image. During the decoding of the enhancement layer bitstream, a context model is maintained using an edge map, and each enhancement layer bitstream is entropy decoded using the context model to determine a significance value corresponding to pixels of the reconstructed residual image and a sign bit for each significant pixel, and a pixel value of the reconstructed residual image is reconstructed according to the significance value, sign bit and an uncertainty interval. Then, the reconstructed residual images are added to the reconstructed base layer image to produce the reconstructed depth image.

摘要： A method compresses a point cloud composed of a plurality of points in a three-dimensional (3D) space by first acquiring the point cloud with a sensor, wherein each point is associated with a 3D coordinate and at least one attribute. The point cloud is partitioned into an array of 3D blocks of elements, wherein some of the elements in the 3D blocks have missing points. For each 3D block, attribute values for the 3D block are predicted based on the attribute values of neighboring 3D blocks, resulting in a 3D residual block. A 3D transform is applied to each 3D residual block using locations of occupied elements to produce transform coefficients, wherein the transform coefficients have a magnitude and sign. The transform coefficients are entropy encoded according the magnitudes and sign bits to produce a bitstream.

摘要： A bitstream includes coded pictures, and split-flags for generating a transform tree. The bit stream is a partitioning of coding units (CUs) into Prediction Units (PUs). The transform tree is generated according to the split-flags. Nodes in the transform tree represent transform units (TU) associated with the CUs. The generation splits each TU only if the corresponding split-flag is set. For each PU that includes multiple TUs, the multiple TUs are merged into a larger TU, and the transform tree is modified according to the splitting and merging. Then, data contained in each PU can be decoded using the TUs associated with the PU according to the transform tree.

摘要： A point cloud encoder including an input interface to accept a dynamic point cloud including a sequence of point cloud frames of a scene. A processor encodes blocks of a current point cloud frame to produce an encoded frame. Wherein, for encoding a current block of the current point cloud frame, a reference block is selected similar to the current block according to a similarity metric to serve as a reference to encode the current block. Pair each point in the current block to a point in the reference block based on values of the paired points. Encode the current block based on a combination of an identification of the reference block and residuals between the values of the paired points. Wherein the residuals are ordered according to an order of the values of the points in the reference block. A transmitter transmits the encoded frame over a communication channel.
