  • Patent number: 10021403
    Abstract: A method of decoding a current block encoded using intra-prediction includes determining prediction modes for coding blocks neighboring the current block. The method generates prediction values for edge samples of the decoded block from intra-prediction reference samples of the neighboring coding blocks by applying an intra-prediction process to the intra-prediction encoded current block if a number of the neighboring coding blocks determined to one of use intra-block copy prediction mode and palette mode is greater than or equal to a predetermined threshold. Alternatively the method generates the prediction values for the edge samples of the decoded block from intra-prediction reference samples of the neighboring coding blocks by applying a filter, preferably an intra-boundary filter, to reference samples of the neighboring blocks. The current block is then decoded based on the prediction values.

  • Patent number: 10013433
    Abstract: A virtual file system is provided. Results are received of a first search for files related to current context of a user of the virtual file system, the files being stored on physical media and/or other virtual file systems. The results of the first search are organized into contextually significant virtual folders of the virtual file system. A first entry is recorded into a history of path mappings which map location of the files in the virtual folders to locations of the files on the physical media. Results are received of a second search for files related to an updated context of the user of the virtual file system. The organization of contextually significant virtual folders is updated based on the results of the second search, and a second entry is recorded into the history of path mappings based on the updated organization.
