| Abstract: | A contour tracking algorithm with simultaneous edge feature detection is proposed and the character contour is separated from the complete graph contour of the scanned image based on rules. For mechanical engineering drawings, the all round neighborhood search method is used to generate the text strings in any orientation. The text strings generated are recognized by a classification tree and corrected with specialized knowledge. Test results show that satisfactory results are given by the method. |
