From said successive downsamplings, the base layer (L0) and the one or more enhancement layers (L1, L2) are constructed, and then an encoded bit stream is prepared in order to be transmitted, comprising data of the base layer and of the enhancement layer or layers. In particular, the downsampling step comprises the application of an adaptive low-pass filter to the image data from the downsampling."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimization of downsampling occurring before encoding images during compression","description":"The disclosure lies in the field of coding image data, scalable in image resolution, such that one or more successive downsamplings are performed from a source signal of maximal image resolution to a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11265563","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.
