Document-Image Related Visual Sensors and Machine Learning Techniques.

Document management systems require document imaging/scanning approaches to convert hard-copy documents/images into digital files. Document imaging/scanning approaches are essential techniques for digitalizing documents in various real-world contexts, e.g., libraries, office communication, management of workflows, and electronic archiving. The documents can then be indexed and the extracted information can be transferred to a document management system for further processing. Since the conversion is not merely an image, Optical Character Recognition (OCR) is consecutively involved in recognizing and extracting the information contained in the document images.
