Normalization and Clipping #138
Comments
Heyho @lcaronson,
sure. In the KiTS19 challenge, we were working on Computer Tomography (CT) scans. Check out this Wikipedia entry for more information: Summarized: These HU values in a CT scan provide exact and detailed information about the tissue.
Clipping is only recommended if you have specific value ranges to exploit. If you are working also on CT data, than I would highly recommend utilizing clipping. The best thing I can advise is to just apply some different clipping ranges on it and have a look on your images if you can still easily detect your ROIs or not. ;) Hope that this answer makes the clipping a bit more clearer. Cheers, |
Hello,
Just hoping for some insight as to why pixel values were clipped from -79 to 304 in the KiTS19 example. Does this relate to the window/level operation on images? I.e. if I am using images with a different contrast distribution, should I consider changing this range to be more appropriate?
Thanks a lot!
Luke
