The described automated system first finds paper documents on a cluttered desk based on a text probability map, constructed using multiple images acquired at fixed grid positions, and then captures a sequence of high-resolution overlapping frames of the located document(s), which are then fused together and perspective-rectified, using computed homography, to reconstruct a high quality and fronto-parallel document image that is of sufficient quality required for optical character recognition. The extracted textual information may be used, for example, for indexing and search, document repository and/or language translation applications."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for detection and high-quality capture of documents on a cluttered tabletop with an automatically controlled camera","description":"Described are systems and methods for recognizing paper documents on a tabletop using an overhead camera mounted on pan-tilt servos.
