Abstract: With the rapid development of graphic image processing technology,image enhancement and recognition methods have been widely used in various industries.On this basis,text recognition technology has also made great progress.Aiming at the problems of shui text random brush strokes,variable fonts and more noise,this paper proposed an improved image enhancement and recognition method.The median filtering algorithm is used to reduce image noise,and the histogram equalization method is used to enhance image contrast.The binarization process is executed to extract the target text in the image,and the corrosion expansion process is executed to refine and expand the background.Finally,the improved text extraction algorithm is used to highlight the outline of the shui text,and the Sobel operator is used to extract the edge of the shui text.The simulation contrast experiment was carried out.The experimental results show that the method effectively reduces image noise,and accurately extracts shui characters.The method can be used in the fields of national character extraction and recognition,cultural relics restoration,image enhancement,etc.It is of great significance for protecting the heritage of ethnic cultural relics and carrying forward the traditional culture of ethnic minorities.

Key words: Histogram equalization, Image enhancement, Image recognition, Shui-character recognition, Text extraction
