Mask values meaning
First of all, thank you very much for releasing the data. I've noticed that there're multiple labels (1-5) in the mask.
What is the meaning of each labels?
The region with the label in {1, 2, 3, 5} is considered as the infarct lesion.
Hi, Kongming, Thanks for your answer! But what about the meaning of value 4? @GriffinLiang
After looking at the dicom data, some of the cases has multiple MRI results. Are the labels 1 to 5 corresponds to different point in time or it corresponds to labelling from different individual?
Some of the lesions may exist on MRI but can be hardly distinguished by the doctors on CT. We label these lesions with the value 4. Different label values are used to reduce the uncertainty of annotations.
Sorry, I still don't understand the difference between 1,2,3 and 5 in the label. (1)Is this labeled by a different person? However, according to the paper, only one doctor marks it and another doctor reviews it. (2)In practice, is it necessary to unify all regions with labels 1,2,3,5 to 1?
