  • Publication number: 20220394246
    Abstract: Methods and apparatus for Adaptive Loop Filter (ALF) processing of reconstructed video are disclosed. According to one implementation, a method receives reconstructed pixels of a current block and determines one or more clipping values for the ALF processing, wherein a target clipping value is always signaled at an encoder side or parsed at a decoder side even if the target clipping value is zero. The method then derives a current ALF output for the current block, wherein the current ALF output has a weighted sum of clipped differences and each of the original differences is calculated between a first reconstructed pixel at a non-center filter location and a center reconstructed pixel at a center filter location, and each of the original differences is clipped according to a corresponding clipping value to form one clipped difference. The method then provides filtered-reconstructed pixels.

  • Publication number: 20220385889
    Abstract: A method and apparatus for video coding using Intra prediction are disclosed. In one method, a first prediction sample in an immediately right column of the current block and a second prediction sample in an immediately below row of the current block are derived using angular prediction. The first prediction sample and a left column reference sample in the same row as the first prediction sample are interpolated to generate a horizontal predictor. The second prediction sample and an above-row reference sample in the same column as the second prediction sample are interpolated to generate a vertical predictor. The vertical predictor and the horizontal predictor are linearly combined to generate an angular-planar prediction sample. In another method, a first predictor is generated using angular prediction and a second predictor is generated using planar prediction. The first predictor and the second predictor are linearly combined to generate a fused Intra predictor.

  • Patent number: 11516513
    Abstract: In one method, the current block is partitioned into multiple final sub-blocks using one or more stages of sub-tree partition comprising ternary tree partition and at least one other-type partition, where ternary partition tree is excluded from the sub-tree partition if a current sub-tree depth associated with a current sub-block is greater than a first threshold and the first threshold is an integer greater than or equal to 1. In another method, if a test condition is satisfied, the current block is encoded or decoded using a current Inter mode selected from a modified group of Inter tools, where the modified group of Inter tools is derived from an initial group of Inter tools by removing one or more first Inter tools from the initial group of Inter tools, replacing one or more second Inter tools with one or more complexity-reduced Inter tools, or both.

  • Patent number: 11509726
    Abstract: Techniques are disclosed for managing media playback among an ad hoc group of playback devices. Such techniques may involve building a session among the playback devices in which playback devices communicate information regarding their playback capabilities. Based on the playback capabilities of the devices, playback mode may be derived for the session. Playback operations may be synchronized among the devices that are members of the session, in which devices receive identification of asset(s) to be rendered pursuant to the playback operation and timing information of playback of the asset. The devices may stream the playback assets directly from media sources when they are capable of doing so. In this manner, communication resources are conserved.

  • Patent number: 11509934
    Abstract: A method and apparatus for video coding incorporating enhanced multiple transform (EMT) are disclosed. According to one method, the number of candidates for EMT in the horizontal direction or vertical direction is reduced depending on the current block size. According to another method, an EMT flag, one or more EMT indices or both are signalled only if the total number of non-zero coefficients in at least a part of the 2D coefficient block is greater than a threshold, where the threshold is equal to 1 or larger. A method and apparatus for video coding using non-separable secondary transform (NSST) are disclosed. According to this method, a total number of non-zero first coefficients in a partial block of the 2D coefficient block is determined and used to determine whether to apply the NSST process.

  • Publication number: 20220361841
    Abstract: Systems, methods, and devices that perform flow scan sequences are provided. In one embodiment, an ultrasound imaging system includes an intraluminal catheter or guidewire, an annular array of acoustic elements positioned around a circumference of the catheter or guidewire, and a processor in communication with the annular array. The processor is configured to activate a first subaperture of the annular array at a first time, thereafter, activate a second interleaving subaperture, and activate the first subaperture again at a different, second time such that the scan sequence moves around the circumference of the catheter or guidewire. Temporal differences between the received ultrasound signals obtained by the first subaperture at the first and second times are determined to detect motion around the annular array. By interleaving subaperture firings, the total number of firings to form an image frame can be reduced.

  • Publication number: 20220359154
    Abstract: This disclosure is directed to solutions of detecting and classifying wafer defects using machine learning techniques. The solutions take only one coarse resolution digital microscope image of a target wafer, and use machine learning techniques to process the coarse SEM image to review and classify a defect on the target wafer. Because only one coarse SEM image of the wafer is needed, the defect review and classification throughput and efficiency are improved. Further, the techniques are not distractive and may be integrated with other defect detecting and classification techniques.
