For a current block of the image, a first pixel is encoded from a prediction value obtained for the first pixel from at least one pixel of a previously rebuilt block. The prediction is corrected using at least one value of a pixel of the correction block. At least one current pixel of the current block is encoded from a prediction value obtained for the current pixel from at least one previously corrected pixel of the current block. The prediction is corrected by using at least one value of a pixel of the correction block, delivering a prediction block for the current block. The residual block is computed from the current block and the predictive block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and devices for coding and decoding a data stream representative of at least one image","description":"A method and device for encoding and a method and device for decoding a signal including encoded data representing an image sub-divided into blocks, and information representing a correction block and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11245924","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.
