摘要： Systems, methods, and computer-readable storage media for restricting block sizes for illumination compensation are described. An example method can include obtaining a block of a picture of video data; determining a size of the block; determining whether the size of the block is equal to or less than a first block size associated with a block size restriction that restricts bi-directional inter-prediction for blocks having a respective size that is equal to or less than the first block size associated with the block size restriction or whether the size of the block is greater than a second block size associated with a video coding pipeline structure; and disabling illumination compensation for the block based on a determination that the size of the block is equal to or less than the first block size or greater than the second block size.

摘要： Systems and techniques for performing illumination compensation in processing video data include deriving one or more illumination compensation parameters for a block of a picture based on one or more tools which may be used for inter-prediction of the block. Illumination compensation can be selectively applied for the block based on whether bi-directional prediction is to be applied for the inter-prediction of the block. In some cases if it is determined that bi-directional prediction is to be applied for inter-prediction of the block, illumination compensation may be avoided for the block.

摘要： Systems and techniques for processing video data include a history-based motion vector predictor (HMVP) table with two or more HMVP candidates, where a first entry of the HMVP table associated with a first index value includes a first HMVP candidate and a second entry of the HMVP table associated with a second index value includes a second HMVP candidate, the first index value being lower than the second index value. For an advanced motion vector prediction (AMVP) candidate list, one or more HMVP candidates from the HMVP table are selected in a reverse order, where the second HMVP candidate is selected before the first HMVP candidate according to the reverse order. The selected one or more HMVP candidates are added to the AMVP candidate list. The AMVP candidate list can be used to perform AMVP for the one or more blocks of video data.

摘要： Techniques are described using Position Dependent Intra Prediction Combination (PDPC) with wide angle intra prediction. For example, a size of the current block of video data can be determined. Based on the size, a wide angle intra-prediction mode can be determined for the current block. A prediction block for the current block can be determined using the wide angle intra-prediction mode. A prediction sample from the prediction block can be modified to generate a modified prediction sample using PDPC, which can include determining one or more reference samples that are external to the current block based on the wide angle intra-prediction mode, and modifying the prediction sample to generate the modified prediction sample based on the determined one or more reference samples.

摘要： Techniques and systems are provided for tracking objects in one or more video frames. For example, a first set of one or more bounding regions are determined for a video frame based on a trained classification network applied to the video frame. The first set of one or more bounding regions are associated with one or more objects in the video frame. One or more blobs can be detected for the video frame. A blob includes pixels of at least a portion of an object in the video frame. A second set of one or more bounding regions are determined for the video frame that are associated with the one or more blobs. A final set of one or more bounding regions is determined for the video frame using the first set of one or more bounding regions and the second set of one or more bounding regions. Object tracking can then be performed for the video frame using the final set of one or more bounding regions.

摘要： Methods, systems, computer-readable media, and apparatuses for gesture recognition are disclosed for audio control. The gestures can be used for audio control in virtualized environments. The audio control can include generating a sound that mimics an effect of a modification of a sound wave that would occur if the gesture were performed in a non-virtualized environment.

摘要： Techniques and systems are provided for processing 360-degree video data. For example, 360-degree video data can be obtained that includes a representation including spherical video data mapped to faces of a geometry. The representation includes a viewport corresponding to an orientation in a 360-degree scene. A window can be determined on a spherical representation of the 360-degree scene at the orientation corresponding to the viewport of the representation. The window is determined based on a front face of the geometry corresponding to the representation. A viewport-aware quality metric can then be determined for the window on the spherical representation of the 360-degree scene.

摘要： Techniques and systems are provided for processing video data. For example, video data can be obtained for processing by an encoding device or a decoding device. Bi- predictive motion compensation can then be performed for a current block of a picture of the video data. Performing the bi-predictive motion compensation includes deriving one or more local illumination compensation parameters for the current block using a template of the current block, a first template of a first reference picture, and a second template of a second reference picture. The templates can include neighboring samples of the current block, the first reference picture, and the second reference picture. The first template of the first reference picture and the second template of the second reference picture can be used simultaneously to derive the one or more local illumination compensation parameters.

摘要： Techniques and systems are provided for processing video data. For example, techniques and systems are provided for matching a plurality of bounding boxes to a plurality of trackers. In some examples, a first association is performed, in which case one or more of the plurality of bounding boxes are associated with one or more of the plurality of trackers by minimizing distances between the one or more bounding boxes and the one or more trackers. A set of unmatched trackers are identified from the plurality of trackers after the first association. The set of unmatched trackers are not associated with a bounding box from the plurality of bounding boxes during the first association. A second association is then performed, in which case each of the set of unmatched trackers is associated with an associated bounding box from the plurality of bounding boxes that is within a first pre-determined distance. A set of unmatched bounding boxes is identified from the plurality of bounding boxes after the second association. The set of unmatched bounding boxes are not associated with a tracker from the plurality of trackers during the second association. A third association is then performed, in which case each of the set of unmatched bounding boxes is associated with an associated tracker from the plurality of trackers that is within a second pre-determined distance.
