In the generating of the predicted values: (i) a predicted value for an upper-layer three-dimensional point in upper layers other than the lower layers among the M layers is generated by a same-layer reference in which another three-dimensional point belonging to a same layer as the upper-layer three-dimensional point is referenced; and (ii) a predicted value for a lower-layer three-dimensional point in lower layers is generated in a condition where the same-layer reference is disabled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three-dimensional data encoding method, three-dimensional data decoding method, three-dimensional data encoding device, and three-dimensional data decoding device","description":"A three-dimensional data encoding method includes: assigning three-dimensional points to M layers, where M is an integer greater than 1; generating respective predicted values of attribute information","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12003767","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.
