The Research and Application of Skew Angle Estimation Technology in Files Digitization
Lai Wen;Archives Center of Guangdong University of Foreign Studies;
Digitalization of archives is a key task in the archives department. However, image slanting inevitably exists in the scanning of paper files, which affects the identification and utilization of OCR files. According to the requirement of "digital specification for paper archives", we need to tilt and correct the scanned images. The author first studies the commonly used text image tilt technology, and chooses the Hough transform based detection method to automatically detect the inclination of the scanned file. The experimental results show that the average detection accuracy of the detection method is 99.02%, and the algorithm is effective.
