Abstract: A method for video decoding is disclosed. A directional intra prediction mode is decoded for a block of a picture, the directional intra prediction mode having a direction. Based on the directional intra prediction mode, a first predictor and a second predictor for a sample in the current block are accessed, the first and second predictors being on a line at least approximating the direction. A sample value of the sample is predicted by interpolation using the first and second predictors, responsive to a difference between the second and first predictors, wherein the difference is scaled by at least a ratio that is based on a location of the sample in the block, and wherein a denominator of the ratio is a power of two regardless of the location of the sample. The sample of the block is reconstructed based on the predicted sample value.

Abstract: An approach is provided that, after receiving a request to execute a computer program, determines an active set of metadata that corresponds to the requested computer program and then loads basic blocks of the requested computer program into memory. One of the loaded basic blocks is a starting block of the requested computer program. The memory also stores basic blocks corresponding to some previously loaded computer programs. The approach also inactivates basic blocks that are currently stored in the memory, with the inactivated basic blocks being identified based on a comparison of the active set of metadata to the sets of metadata that corresponding to the basic blocks of previously loaded computer programs. After inactivating some basic blocks, the approach executes the starting block of the requested computer program.

Abstract: Described herein are systems, methods, and non-transitory computer readable media for validating or rejecting automated detections of an entity being tracked within an environment in order to generate a track representative of a travel path of the entity within the environment. The automated detections of the entity may be generated by an artificial intelligence (AI) algorithm. The track may represent a travel path of the tracked entity across a set of image frames. The track may contain one or more tracklets, where each tracklet includes a set of validated detections of the entity across a subset of the set of image frames and excludes any rejected detections of the entity. Each tracklet may also contain one or more user-provided detections in scenarios in which the tracked entity is observed or otherwise known to be present in an image frame but automated detection of the entity did not occur.

Abstract: Methods, systems, and devices for wireless communications are described. A set of uplink control channel resources that are configured for acknowledgment transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of uplink control channel resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel. After failing to receive a multicast transmission, UEs may transmit an acknowledgment feedback message over one of the shared uplink control channel resources that is associated with the set of channel state information determined by the UE. A base station that receives the acknowledgment feedback message may transmit a multicast retransmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied uplink control channel resource.

Abstract: A method is provided for checking engagement and disengagement of a parking brake finger, which selectively blocks or blocks a shaft of the transmission. A motor-driven rotary selection plate is selectively controlled to butt against the transmission casing at the two ends of its travel, and is immobilized therebetween in a first functional engagement position and in a second functional disengagement position that correspond to the Park and non Park positions of the parking brake finger when the drive motor of the plate stops exerting torque thereon. The angular movements of the plate between its abutment positions are measured and incremented using a computer to determine whether the engagement position and disengagement position of the plate that is reached every time the drive motor is stopped corresponds to a command instruction given to the motor.

Abstract: A system can automatically adjust a virtual background used by a participant in a video conference to match lighting level conditions present in a foreground of a participant video stream captured at a participant device. The matching can be done by adjusting one or more virtual background parameters, including but not limited to, exposure, brightness, contrast, and ISO. In some implementations, the system can dynamically or automatically adjust the lighting levels of the virtual background based on changes that may occur to the lighting level of the foreground during the video conference.
