The method includes: performing preprocessing and object labeling on images; modifying an Oquab network to be a local model for four classes through transfer learning and training the local model; training two pairwise models of head and ear as well as body and head based on the local model; and performing joint detection for an ear through the local model, the two pairwise models and body features. The method uses a hierarchical relationship from large to small to establish contextual information, which can reduce the interference of other features and detect the location of the ear more accurately."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ear detection method with deep learning pairwise model based on contextual information","description":"An ear detection method with deep learning pairwise model based on contextual information belongs to the field of biometric recognition technologies, and addresses a problem that an ear location canno","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11521427","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.
