Manchu Text Extract Under the Image Background
Zhu Man-qion · Dalian Minzu Xueyuan xuebao · 2014
Based on the structure and characteristic of Manchu,this paper elaborates a new stroke extraction method. Firstly,the digital image processing method is used to extract the Manchu character from an image background picture,perform such preprocessing methods as de- noising,thinning,pruning and so on. Then the mid- axis of Manchu character,termination point,interior points and intersection points are found. Moreover,the critical point on the mid- axis is achieved. The critical point by using the stroke growth algorithm is used to separate the stroke so as to achieve the purpose of Manchu text stroke extraction. To verify the feasibility of the method,this paper carries out a text extraction on handwritten Manchu,printed Manchu and Manchu in the color image. Simulation results show that the method is effective in separating the Manchu stroke and will lay a solid foundation for the further study of Manchu identification.
