I have the following raw image it’s a slice from a 3D CT scan (raw data is 5GB containing 4200 slices) . It’s a cylinder part of 5mm in diameter printed using SLM process (additive manufacturing). I need to remove the background in order to make analysis like detecting the porosity defects in this cylinder part. But as a first step i need to select the region of interest. Since the image is not a circle a manual ROI then clear outside is not sufficient so I am using Weka segmentation. Is there a way to get the ROI from the segmentation? Or is there a better way to remove the background for my type of data .
I’m trying to do the traitement on this slice then generalise it in the 3D scan .
PS : I’m using ImageJ 2.1.0/1.53c;Java 1.8.0_202[64-bit]
Thank you in advanced
