摘要： Techniques and systems are provided for prioritizing objects for object recognition in one or more video frames. For example, a current video frame is obtained, and a objects are detected in the current video frame. State information associated with the objects is determined. Priorities for the objects can also be determined. For example, a priority can be determined for an object based on state information associated with the object. Object recognition is performed for at least one object from the objects based on priorities determined for the at least one object. For instance, object recognition can be performed for objects having higher priorities before objects having lower priorities.

摘要： Methods and systems for processing video data are provided. In one example, a first video bitstream can be obtained, which can include video frames of a spherical representation of 360-degree video data. Two-dimensional pixel coordinates of a pixel location of a planar surface of a geometry can be determined. The planar surface can be part of a plurality of planar surfaces of the geometry. Two-dimensional normalized coordinates can be determined for the pixel location based on an adaptation parameter and the two-dimensional pixel coordinates. Three-dimensional coordinates of a sample point of the spherical representation of the 360-degree video data can be determined based on the two-dimensional normalized coordinates. A pixel value for the pixel location of the planar surface of the geometry can be determined based on the sample point, and a second video bitstream can be generated that includes pixel values determined for pixel locations of the plurality of planar surfaces of the geometry.

摘要： Techniques are provided for estimating a three-dimensional pose of an object. An image including the object can be obtained, and a plurality of two-dimensional (2D) projections of a three-dimensional bounding (3D) box of the object in the image can be determined. The plurality of 2D projections of the 3D bounding box can be determined by applying a trained regressor to the image. The trained regressor is trained to predict twodimensional projections of the 3D bounding box of the object in a plurality of poses, based on a plurality of training images. The three-dimensional pose of the object is estimated using the plurality of 2D projections of the 3D bounding box.

摘要： Techniques and systems are provided for processing video data. For example, 360-degree video data can be obtained for processing by an encoding device or a decoding device. The 360-degree video data includes pictures divided into motion-constrained tiles. The 360-degree video data can be used to generate a media file including a plurality of tracks. Each of the plurality of tracks contain a set of at least one of the motion-constrained tiles. The set of at least one of the motion-constrained tiles corresponds to at least one of a plurality of viewports of the 360-degree video data. A first tile representation can be generated for the media file. The first tile representation encapsulates a first track of the plurality of tracks, and the first track includes a first set of at least one of the motion-constrained tiles at a first tile location in the pictures of the 360-degree video data. The first set of at least one of the motion-constrained tiles corresponds to a viewport of the 360-degree video data.

摘要： To determine real-world information about objects moving in a scene, the camera capturing the scene is typically calibrated to the scene. Automatic scene calibration can be accomplished using people that are found moving about in the scene. During a calibration period, a video content analysis system processing video frames from a camera can identify blobs that are associated with people. Using an estimated height of a typical person, the video content analysis system can use the location of the persons head and feet to determine a mapping between the persons location in the 2-D video frame and the persons location in the 3-D real world. This mapping can be used to determine a cost for estimated extrinsic parameters for the camera. Using a hierarchical global estimation mechanism, the video content analysis system can determine the estimated extrinsic parameters with the lowest cost.

摘要： Techniques and systems are provided for processing video data. For example, techniques and systems are provided for performing context-aware object or blob tracker updates (e.g., by updating a motion model of a blob tracker). In some cases, to perform a context-aware blob tracker update, a blob tracker is associated with a first blob. The first blob includes pixels of at least a portion of one or more foreground objects in one or more video frames. A split of the first blob and a second blob in a current video frame can be detected, and a motion model of the blob tracker is reset in response to detecting the split of the first blob and the second blob. In some cases, a motion model of a blob tracker associated with a merged blob is updated to include a predicted location of the blob tracker in a next video frame. The motion model can be updated by using a previously predicted location of blob tracker as the predicted location of the blob tracker in the next video frame in response to the blob tracker being associated with the merged blob. The previously predicted location of the blob tracker can be determined using a blob location of a blob from a previous video frame.

摘要： Techniques and systems are provided for maintaining lost blob trackers for one or more video frames. In some examples, one or more blob trackers maintained for a sequence of video frames are identified. The one or more blob trackers are associated with one or more blobs of the sequence of video frames. A transition of a blob tracker from a first type of tracker to a lost tracker is detected at a first video frame. For example, the blob tracker can be transitioned from the first type of tracker to the lost tracker when a blob for which the blob tracker was associated with in a previous frame is not detected in the first video frame. A recovery duration is determined for the lost tracker at the first video frame. For one or more subsequent video frames obtained after the first video frame, the lost tracker is removed from the one or more blob trackers maintained for the sequence of video frames when a lost duration for the lost tracker is greater than the recovery duration. The blob tracker can be transitioned back to the first type of tracker if the lost tracker is associated with a blob in a subsequent video frame prior to expiration of the recovery duration. Trackers and associated blobs are output as identified blob tracker-blob pairs when the trackers are converted from new trackers to trackers of the first type.

摘要： Techniques and systems are provided for processing video data. For example, techniques and systems are provided for performing content-adaptive object or blob tracking. To perform the content-adaptive object tracking, a blob tracker is associated with a blob generated for a video frame. The blob includes pixels of at least a portion of a foreground object in a video frame. A size of the blob can be determined to be greater than a blob size threshold. The blob tracker can be converted to a normal tracker based on the size of the blob being greater than the size threshold. The associated blob tracker and blob are output as an identified blob tracker-blob pair when the blob tracker is converted to the normal tracker.
