I used the script here to do projection information extraction, projection alignment, hot spot removal and reconstruction on a XRF tomography dataset from 2ide. The goal of the data analysis is to generate 3D information for users to do 3D printing.
- extract the angle information from h5 file and check usable projection images
- when aligning the projection, a hot spot was used as rotation center, however, it introduce stripes in reconstruction. I used local maximum method to remove the hot spot. I used tomviz to do projection alignment.
- reconstruction is done by tomopy
- segmentation: I tried kmean and watershed (used for another TXM dataset)
- visualization: Tomviz (save as STL file)
