What is the minimum intensity in test dataset

In training dataset , the minimum image intensity is -1000, but in GitHub, the minimum intensity of two test images is 0. So I want to know, what is the minimum intensity in test dataset?

Hi Zhendong Yang, Unfortunately, we cannot provide any information regarding the private test dataset. CBCT scanners' intensity usually varies from −1500 to over +5000, so you can expect this kind of range too in the test set. The test on GitHub was probably preprocessed by clipping the range to [0, 2100] as we do in the PosPadUNet3D paper. This kind of preprocessing will obviously not be applied to the testing images.
