| Abstract: | An effective method for steel number extraction and segmentation under complex background is presented in this paper. Based on the HSV color model, the method regards the saturation as principle to distinguish the foreground and background, then uses mathematic morphological operation and boundary detection technique to extract valid district of steel pieces. The multi-projection histograms are proposed to segment the code in the line and row, and it also solves interference and conglutination problems, achieves accurate location of the number. The practical results show that the segmentation method is good. |
