Abstract: An object detection algorithm is selectively applied to frames in a video. A frame in the video is analyzed using a set of neural networks of the object detection algorithm to detect a location of an object in the frame and predict a bounding box for the object in the frame.

The magnitude of the delta is determined based on a difference between the two frames in values of at least one parameter of their respective sets of pixels. Responsive to the magnitude of the delta being less than a threshold, a new bounding box is predicted for the object in the second frame without analyzing the second frame using the set of neural networks.

Abstract: Methods and devices for encoding and decoding video are described that partition transform blocks into coefficient groups. The coefficients within non-zero coefficients are run-length coded in a reverse scan order within the group. Prior to coefficient coding, data is encoded indicating which coefficient group in group scan order is the last to contain a non-zero coefficient.

Abstract: In a video coding apparatus, a plurality of coding units perform compression coding of a single source stream of video data. A control unit controls those coding units in such a way that all the coding units produce respective interframe coded pictures with identical playback times as a first-coded picture in a picture group (e.g., GOP) and produce identical local decoded pictures based on the respective intraframe coded pictures.

According to this selection, a selection unit selectively outputs one of the coded video data. This output switching operation is performed at a point immediately before a forward interframe predictive coded picture that appears first of those in a picture group included in each of the coded video data outputs being switched.
