  • Publication number: 20220210423
    Abstract: A video coder may code a block of video data using an intra prediction mode determined from a most probable mode list. The video coder may construct a general most probable mode list containing N entries, wherein the N entries of the general most probable mode list are intra prediction modes, and wherein a planar mode is an ordinal first entry in the general most probable mode list, construct a primary most probable mode list from a first Np entries in the general most probable mode list, where Np is less than N, and construct a secondary most probable mode list from a remaining (N-Np) entries in the general most probable mode list. The video coder may then determine a current intra prediction mode for a current block of video data using the primary most probable mode list or the secondary most probable mode list.

  • Patent number: 11374127
    Abstract: A device, structure, and method are provided whereby an insert layer is utilized to provide additional support for weaker and softer dielectric layer. The insert layer may be applied between two weaker dielectric layers or the insert layer may be used with a single layer of dielectric material. Once formed, trenches and vias are formed within the composite layers, and the insert layer will help to provide support that will limit or eliminate undesired bending or other structural motions that could hamper subsequent process steps, such as filling the trenches and vias with conductive material.

  • Patent number: 11350082
    Abstract: A method of decoding a bitstream by an electronic device is provided. A block unit having an intra prediction mode is determined from an image frame according to the bitstream. The intra prediction mode is determined based on a first one of a plurality of mode indices, when a reference line index (Refidx) is different from a first predefined value. The intra prediction mode is determined based on the first mode index, when the Refidx is equal to the first predefined value and a most probable mode (mpm) flag is equal to a second predefined value. The intra prediction mode is determined based on a second one of the mode indices, when the Refidx is equal to the first predefined value and the mpm flag is different from the second predefined value. Then, the block unit of the image frame is reconstructed based on the intra prediction mode.

    Abstract: A stream of virtual topograms, in particular live virtual topograms, is predicted. Sets of surface data of an outer surface of a subject are continuously received. Based on each received set of surface data a (live) virtual topogram is continuously generated by a trained machine learning algorithm (MLA). Thereto, a representation of body landmarks is updated based on each received set of surface data by a trained body marker detector (BMD), of the trained MLA, and the (live) virtual topogram is predicted based on the updated spatial marker map and on the corresponding set of surface data by a trained topogram generator (TG) of the trained MLA.

  • Patent number: 11313869
    Abstract: A method of characterizing a serum and plasma portion of a specimen in regions occluded by one or more labels. The characterization may be used for Hemolysis, Icterus, and/or Lipemia, or Normal detection. The method captures one or more images of a labeled specimen container including a serum or plasma portion, processes the one or more images to provide segmentation data and identification of a label-containing region, and classifying the label-containing region with a convolutional neural network (CNN) to provide a pixel-by-pixel (or patch-by-patch) characterization of the label thickness count, which may be used to adjust intensities of regions of a serum or plasma portion having label occlusion. Optionally, the CNN can characterize the label-containing region as one of multiple pre-defined label configurations. Quality check modules and specimen testing apparatus adapted to carry out the method are described, as are other aspects.
