Sorry, I often ask questions in this forum recently. Because I’ve been studying image processing attentively for the past half month, I have another problem now…
I want to give my segmentation result clean up. The small isolated cluster of void and grain voxels may strongly distort the skeletonization process. So I need to do a size filter for my segmentation images. In this regard, I think of 3D Object Count or BoneJ-Particle Analyze can achieve this.
I would like to remove small isolated cluster grain voxels first. In 3D Object Count, I set the size filter is 10-2400000. But the result shows：
0 objects detected (Size filter set to 10-2400000 voxels, threshold set to 128).
I doubt it, because at least can be filter a few in Bonej-Particle Analyze.
And even if I set the size filter to 30-2400000 voxels, it also doesn’t work.
1. Why is that? Why can’t use 3D Object Count to do size filter？
Then I used BoneJ-Particle Analyze to make a size filter(10-2400000 pixel^3).
By comparison, at least it has come to an end, but it doesn’t feel perfect. Because I think it makes size filter only in the first slice.
2. So I want to ask you to confirm that the size filter in Bonej-Particle Analyze works for the whole stack? Or just one slice?
3. The size filter unit in Bonej-Particle Analyze is pixel^3. What is the unit in 3D Object Count? Because there is no specific description. If it’s also pixel^3, why it show not found in 3D Object Count?
