| Abstract: | The double thresholds binarization and morphological transform are applied to preprocess the metal micro-image.They can classify the grain and the grain boundary.Then a filling-elimination method has been produced for counting the number of grains in the micro-image,and also a equation for calculating grain size has been presented.They will bring a stability foundation for the deep metallographical analysis. |
