I am asking for advice about the best way to segment a tooth from a fossil mandibular fragment. This is from a mCT scan of 1,554 slices. I want to segment enamel, dentine, pulp, and roots etc… but densities are extremely similar!
There is really no magical formulas to separate enamal, dentine pulp and roots if the intensities are very similar. Normally enamel should be easy, but you said this is a fossil so diagenesis would change that. You can try the NNInteractive, AI-based interactive segmentation, but you will probably first reduce the resolution of your dataset (probably by factor of 2).
