The method is used to perform virtual 3D model reconstruction with physical rationality for individual hairstyles in single-views and video sequences, and widely applied in creating virtual characters and many hairstyle editing applications for images and videos."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for image and video virtual hairstyle modeling","description":"The invention discloses a method for image and video virtual hairstyle modeling, including: performing data acquisition for a target subject by using a digital device and obtaining a hairstyle region ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9792725","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.
