By applying the encoding method, better prediction accuracy can be achieved when the image block presents a small change of pixel value in the horizontal or vertical direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Encoding and decoding methods and apparatuses with multiple image block division manners","description":"An encoding method with multiple image block division manners is disclosed, including: determining a division manner and a division direction of an image block; dividing the image block to obtain imag","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11290717","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.
