Description: Image processing technology in the Marking System
Abstract: The analysis of the characteristics of the answer sheet, an image designed to determine whether the answer sheet, research and improved gray-scale color image processing algorithms in addition to the color of the image recognition of the interference, The data obtained so easy to deal with the root. In the image correction section analysis of the image deflection phenomenon and, based on feature points collected on the value of design angle calculation algorithm, designed for the answer card, image rotation algorithm, the image of the deflected appropriate adjustments to Rating graders meet the requirements of key words: image processing scoring system answer sheet
