The method confirms the scan boundary of a document and is not subjected to a backlight element or a document carrier. The method identifies the boundary of a document under a non-unified background, is applicable to scanning transparent and reflective documents and has strong resistance against environmental interference, not only simplifying the scanning device but also enhancing the automatic performance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for automatically identifying scan region boundary","description":"A method of automatically identifying a scan region boundary, used for scanning a document under a non-unified background, includes: reading a reference linear scan data by a scanning device, the scan","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493634","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.
