A bitstream of data corresponding to an image having pre-determined multiple regions is received, and a number is determined from the bitstream corresponding to a number of filters in an adaptive loop filter associated with the image. A region index to filter an index lookup table is decoded. The filter coefficients of the filters in the adaptive loop filter are decoded. The image is decoded based on the decoded filter coefficients and the decoded region index to filter the index lookup table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Region adaptive loop filter for video coding","description":"A method, computer program, and computer system is provided for video encoding and decoding.
