The signature is generated by applying a hash function to values derived from the average and variance composite representations. The video content of a signal can be represented by a set of signatures that are generated for multiple series of frames within the signal. A set of signatures can provide reliable identifications despite intentional and unintentional modifications to the content."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Deriving video signatures that are insensitive to picture modification and frame-rate conversion","description":"A signature that can be used to identify video content in a series of video frames is generated by first calculating the average and variance of picture elements in a low-resolution composite image th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8488061","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.
