Grain size analysis in steel
In this example, Clemex Vision system is selected to measure the grain size of steel in accordance with ASTM E112.
Figure 1. The original image of etched steel before Gray Thresholding is viewed at 100X magnification.
Figure 2. Binarization of the original image into the blue bitplane using Gray Thresholding; (Right) Artifacts were removed and the network was inverted to obtain the grains. Touching grains were separated using Convex Hull, Separate and Zone binary transformations.
Figure 3.Binarization of the original image into the blue bitplane using Gray Thresholding; (Right) Artifacts were removed and the network was inverted to obtain the grains. Touching grains were separated using Convex Hull, Separate and Zone binary transformations.
