Application of Mathematical Morphologic Process in Character Recognition
形态学运算在字符识别中的应用

As a basic recognize technique,character recognition is widely used in computer input,traffic,security keeping and other fields.Before characters are recognized,we must do a series of preprocessings to the original image in order to extract their characteristics,such as Gray Stretch,Threshold Transform and so on.These preprocessings can strengthen the characteristics of target characters and get rid of noises.However,they often make the strokes of the target characters broken.Because the structure of the strokes is very thin,normal morphologic opening or closing process will break the strokes more seriously.By reforming the morphologic closing process,this paper proposes a process to eliminate the breaks of target characters.Experiment results show that the process is effective.
