Described are systems and methods for recognizing paper documents on a tabletop using an overhead camera mounted on pan-tilt servos. 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.
A computer-implemented method being performed in a computerized system comprising a processing unit, a memory and a camera, the camera being mounted on a turret operatively coupled to the processing unit, the computer-implemented method comprising:
A non-transitory computer-readable medium embodying a set of computer-executable instructions, which, when executed in a computerized system comprising a processing unit, a memory and a camera, the camera being mounted on a turret operatively coupled to the processing unit, cause the computerized system to perform a method comprising:
A computerized system comprising a processing unit, a memory and a camera, the camera being mounted on a turret operatively coupled to the processing unit, the memory storing a set of computer-executable instructions causing the computerized system to perform a method comprising:
