Abstract: Techniques and systems are provided for maintaining blob trackers for one or more video frames. For example, a blob tracker is identified for a current video frame. The blob tracker is associated with a blob detected for the current video frame. The blob includes pixels of at least a portion of one or more objects in the current video frame. A current characteristic of pixels in a region of the current video frame associated with the blob tracker is determined. A previous characteristic of pixels in a region of a previous video frame associated with the blob tracker is also determined. A difference is determined between the current characteristic and the previous characteristic, and a status of the blob tracker is determined based on the determined difference. The status of the blob tracker indicating whether to maintain the blob tracker for the one or more video frames.

Abstract: A video coder determines a first disparity vector using a first disparity vector derivation process. In addition, the video coder determines a second disparity vector using a second disparity vector derivation process. The first disparity vector derivation process is different than the second disparity vector derivation process. The video coder uses the first disparity vector to determine a motion vector prediction (MVP) candidate in a set of MVP candidates for a current prediction unit (PU). The video coder uses the second disparity vector to determine residual data.

Abstract: As one example, a method of coding video data includes storing one or more decoding units of video data in a coded picture buffer (CPB). The method further includes obtaining a respective buffer removal time for the one or more decoding units. The method further includes removing the decoding units from the CPB in accordance with the obtained buffer removal time for each of the decoding units. The method further includes determining whether the CPB operates at access unit level or sub-picture level. The method further includes coding video data corresponding to the removed decoding units. If the CPB operates at access unit level, coding the video data comprises coding access units comprised in the decoding units. If the CPB operates at sub-picture level, coding the video data comprises coding subsets of access units comprised in the decoding units.
