The video coding method further includes outputting an enhanced frame or a virtual reference picture by generating a feature map with different levels, based on the current reference frame, a first reference frame and a second reference frame, generating a predicted frame based on aligned features from the generated feature map by refining the current reference frame, the first reference frame, and the second reference frame, generating a final residual based on the predicted frame, and computing the enhanced frame as an output by adding the final residual to the current reference frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for deep neural network based inter-frame prediction in video coding","description":"Video coding using neural network based inter-frame prediction is performed by generating a current reference frame by generating intermediate flows based on two input frames, performing backward warp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11490078","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.
