Abstract: An encoded bitstream of entropy encoded video data is received by a video decoder. The encoded bitstream represents syntax elements of a sequence of coding blocks. The sequence of coding blocks is recovered by processing a bin sequences associated with each coding block in a processing pipeline, wherein a defined amount of time is allocated to process each coding block in the processing pipeline. The encoded bitstream is arithmetically decoded to produce each bin sequence. The arithmetic decoder is time-wise decoupled from the processing pipeline by storing a plurality of the bin sequences in a buffer memory.

Abstract: A method for boundary partition of a current block is provided. The method includes obtaining a partition indicator from a received bitstream; determining whether the partition indicator indicates that the current block is to be split and whether the current block is a boundary block; and performing a non-inverse transform operation on an inside part of the current block when the partition indicator indicates that the current block is not to be split and the current block is a boundary block, wherein the inside part of the block is located within the picture. For the boundary block which is determined not to be split, a non-inverse transform operation is chosen. This avoids a normal inverse transform on the residuals of the inside part (within the picture) of the current block in the decoder, so number of blocks for the inverse transformation is decreased, and decoding complexity is thus reduced.

Abstract: Systems and techniques are described for large field of view digital imaging. A device's first image sensor captures a first image based on first light redirected from a first path onto a redirected first path by a first light redirection element, and the device's second image sensor captures a second image based on second light redirected from a second path onto a redirected second path by a second light redirection element. A virtual extension of the first path beyond the first light redirection element can intersect with a virtual extension of the second path intersect beyond the second light redirection element. The device can modify the first image and second image using perspective distortion correction, and can generate a combined image by combining the first image and the second image. The combined image can have a larger field of view than the first image and/or the second image.

Morton codes for a point cloud are obtained according to geometry information of the point cloud. The point cloud is determined as an input point cloud of an iteration.

A point is selected from points with a same value of Morton codes after right shifted by K bits. An i-th level of detail (LOD) layer is formed with the point selected.

Abstract: An encoder and a decoder are provided for encoding, and decoding pictures, respectively. The encoder defines a structure for a picture segment by dividing the picture into multiple picture segment groups and assigning a unique group ID to each group. Each picture segment group is further divided into one or more picture segments or “tiles,” with each picture segment being assigned the ID of its picture segment group. The encoder then encodes the picture segments of the picture segment groups into a bit stream, and sends the bit stream to the decoder. Upon receiving the bit stream, the decoder extracts each picture segment group as a single entity and decodes the picture segments in each picture segment group in a predetermined order.
