In this paper,the methods of text line segmentation and character segmentation are proposed according to the characteristics of historical Chinese documents.The method of line segmentation analyzes stroke projection,and adopts a recursive segmentation algorithm based on various project thresholds and gap thresholds.This algorithm is robust in the cases of text line adhesion and skew,especially short text lines.The method of character segmentation has two steps.A rough segmentation is applied to get the approximate positions of segmentation.A fine segmentation based on the analysis of connected components and the judgment of adhesion points is carried out.This algorithm can extract the characters even though they overlap and connect each other.The experimental results show the methods have good performance and are suitable for the segmentation of historical Chinese documents.
