I am new to imageJ and want to analyze the fracture surface of a 3D printed Aluminum. The fracture surface was imaged using SEM (secondary electron mode), Jimage_fail20191016.000005.tif (1.2 MB), (288 pixels equals 1 mm). As can be seen in the attached file, the fracture surface contains many defects. I want to know the area covered by these defects as to compare them for different samples. In my first attempts I used the following procedure:
- Apply Bypass filter
- Threshold the image
- Analyze particles
I was able to get a percentage of defects covering the surface area. However, the results are not reproducible and deviate quite a bit. I reckon I need to apply more filters before Thresholding, unfortunately I do not know which to use.
Any tips would be very much appriciated !
