Intelligent Recognition of Specific Information in Document Images
Chen Xiao-su · Computer Engineering and Science · 2004
This paper discusses a document image analysis system based on optical mark recognition. The design method and implementation techniques are emphasized. We use mark recognition as an example to describe the key components of the system, image digitalization, preprocessing of images, image information acquisition and feature extraction. A highly practical and efficient boundary detection algorithm is presented in preprocessing. Statistical analysis is applied to mark feature extraction. These methods greatly enhance the recognition rate.
