The in-loop filter apparatus comprises a processing unit configured to: partition the reconstructed frame into a plurality of overlapping and/or non-overlapping 2D pixel blocks; generate for each 2D pixel block a 2D spectrum by applying a 2D transform to the 2D pixel block, wherein the 2D spectrum comprises a plurality of spectral components; generate for each 2D pixel block a filtered 2D spectrum by multiplying each spectral component with a respective gain coefficient, wherein the respective gain coefficient depends on the respective spectral component and/or one or more neighboring spectral components of the respective spectral component and one or more filtering parameters; generate for each 2D pixel block a filtered 2D pixel block by applying an inverse 2D transform to the filtered 2D spectrum; and generate the filtered reconstructed frame on the basis of the plurality of filtered 2D pixel blocks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-loop filter apparatus and method for video coding","description":"The disclosure relates to an in-loop filter apparatus for video coding, which is configured for processing a reconstructed frame corresponding to a current frame for generation of a filtered reconstru","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11265582","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
