  • Publication number: 20240244182
    Abstract: A video bitstream including coding information of a current block in a current picture is received, where the coding information indicates that the current block is coded with an intra template matching prediction mode. At least one template for predicting the current block is determined. Each of the at least one template is a respective candidate template of a plurality of template types available in the intra template matching prediction mode. The candidate templates are associated with one of a shape of the current block, a size of the current block, an intra prediction mode of the current block, and distances between the current block and the candidate templates of the plurality of template types. The candidate templates include different combinations of neighboring reconstructed samples. The current block is reconstructed using template match in the intra template matching prediction mode based on the determined at least one template.

  • Publication number: 20240240244
    Abstract: A methylation detection method and kit for genomic DNA or cell-free DNA molecules in a biological sample are provided. The method includes: obtaining a converted DNA molecule through a chemical and/or enzymatic reaction; performing a methylation-specific multiplex PCR, through multiple pairs of methylation-specific primers, on one or more methylated areas of one or more genes in the converted DNA molecule serving as a substrate, in order to obtain a PCR amplification product; and detecting the methylation levels of different fragments of the amplification product. The detection method can detect DNA methylation in multiple genes in multiple samples at the same time, requires only a small initial amount of DNA, is suitable for detecting methylated fragments having a small copy number, and has such advantages as high sensitivity, high specificity, high accuracy, a low detection limit, and low detection cost.

  • Publication number: 20240244188
    Abstract: Aspects of the disclosure provide a method, an apparatus, and non-transitory computer-readable storage medium for video decoding. The apparatus includes processing circuitry configured to reconstruct an area in a block in a current picture from a coded video bitstream. The block includes one or more coding blocks (CBs) in the current picture. After the reconstructing, the processing circuitry determines whether to update a previous local reference range for an intra block copy (IBC) mode based on a content of the reconstructed area and/or prediction information of the reconstructed area. In response to a determination not to update the previous local reference range for the IBC mode, the previous local reference range for the IBC mode is not updated. The processing circuitry decodes a coding block in the current picture using the IBC mode that is based on the previous local reference range, which does not include the reconstructed area.
