Abstract: A video encoder and video decoder are configured to encode and decode blocks of video data using affine motion prediction. Affine motion prediction may include predicting control point motion vectors using an affine advanced motion vector prediction (AMVP) motion vector predictor list. The video encoder and video decoder may be configured to construct the affine AMVP motion vector predictor list of candidate control point motion vectors for the block of video data, wherein the affine AMVP motion vector predictor list includes one or more affine motion vector predictors that have all control point motion vectors equal to a designated motion vector.

Abstract: Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled. This permits a decoder to determine which pictures are expected to be available for reference from the signaled state information. For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB. The encoder then outputs the syntax elements as part of a bitstream.

For example, the system can detect the presence of the bubble within the primary substance along the part of the fluid line, which can include assigning a digital signature to the bubble. In addition, the system can track the movement of the bubble in order to ensure that the bubble is accounted for only once as it passes through the part of the fluid line. Furthermore, the system can analyze the bubble, such as determine its direction of travel, speed of travel, volume and size.

Abstract: Various aspects of the subject technology relate to prediction of eye movements of a user of a head-mountable display device. Predictive foveated display systems and methods, using the predicted eye movements are also disclosed. Predictive variable focus display systems and methods using the predicted eye movements are also disclosed. Predicting eye movements may include predicting a future gaze location and/or predicting a future vergence plane for the user's eyes, based on the current motion of one or both of the user's eyes. The predicted gaze location may be used to pre-render a foveated display image frame with a high-resolution region at the predicted gaze location. The predicted vergence plane may be used to modify an image plane of a display assembly to mitigate or avoid a vergence/accommodation conflict for the user.

Abstract: A deblocking filtering control involves deciding whether to apply deblocking filtering to sample values in a sample block in a picture and in a neighboring sample block in the picture based on i) a first magnitude modification of sample prediction values in a first prediction block in a reference picture for the sample block and ii) a second magnitude modification of sample prediction values in a second prediction block in the reference picture for the neighboring sample block. The sample block and the neighboring sample block are separated in the picture by a block boundary. This decision to apply deblocking filtering based on magnitude modifications reduce blocking artefacts that may otherwise arise in certain pictures of a video sequence.
