Abstract: A video coder may code a sign prediction syntax element that indicates whether a sign prediction hypothesis is correct for a transform coefficient. The video coder may code the sign prediction syntax element using a context-based coding process. The video coder may determine a context for coding the sign prediction syntax element based on a position of the transform coefficient in the block of video data. The context may be further based on a coding mode used to code the block.

Abstract: In some examples, a method of decoding a point cloud includes determining a first slice QP value for a first component of an attribute in a slice of point cloud data. The method also includes decoding a first delta QP value for the first component of the attribute for a region in the slice and determining a first region QP value for the first component of the attribute in the region from the first slice QP value and from the first delta QP value. The method further includes decoding a second delta QP value for the second component of the attribute for the region and determining a second region QP value for the second component of the attribute in the region from the second delta QP value. The method includes decoding the point cloud data based on the first and second region QP values.

Abstract: A method for decoding point cloud data comprises, based on a comparison of a maximum difference value and a threshold, applying an inverse function to a set of one or more jointly coded values to recover (i) residual values for attribute values of a current point of point cloud data and (ii) a predictor index that indicates a predictor in a predictor list, wherein predictors in the predictor list are based on attribute values of one or more neighbor points; determining predicted attribute values based on the predictor index; and reconstructing the attribute values of the current point based on the residual values and the predicted attribute values.

Abstract: This disclosure provides systems, methods, and devices for vehicle driving assistance systems that support image processing. In a first aspect, a method includes receiving a first image frame from a first camera; receiving second image frame from a second camera. The fields-of-view of the cameras partially overlap. A set of coordinates associated with pixel values of the first image frame and pixel values of the second image frame are determined. The set of coordinates correspond to an overlap of the first field-of-view and the second field-of-view. A first uncertainty window metric is determined based the set of coordinates and first uncertainty values. A second uncertainty window metric is determined based on the first uncertainty values and second uncertainty values associated with RADAR. Fused depth data is determined based on the set of coordinates, the RADAR data, and the first and second uncertainty window metrics. Other aspects and features are also claimed and described.

Abstract: An example device includes one or more memories configured to store a current real-time transport protocol (RTP) packet and one or more processors. The one or more processors are configured to determine a protocol data unit (PDU) set, the PDU set comprising a plurality of PDUs, each PDU comprising a corresponding RTP packet. The one or more processors are configured to determine, for a current RTP packet of the PDU set, a remaining PDU set size, the remaining PDU set size being indicative of a size of the sum of a remainder of the PDUs of the PDU set. The one or more processors are configured to transmit the current RTP packet including an RTP header extension comprising a value indicative of the remaining PDU set size.

Abstract: An example device for decoding point cloud data includes: a memory configured to store point cloud data; and one or more processors implemented in circuitry and configured to: decode a frame of the point cloud data including a plurality of points, each of the points being associated with position values defining a respective position of the point; determine a global scaling factor for the frame; and scale the position values of each of the points by the global scaling factor. The scaling may be clipped to prevent the points exceeding the boundaries of a corresponding bounding box including respective points.
