mean Dice of multi-class segmentation

[YingdiZhang]

Thanks for the great work.
I wonder how to calculate the mean dice in a multi-class segmentation task.
It means for example in a 7 class segmentation task, I want to get one mean dice instead of 7 seperate dice

Hi @YingdiZhang ,

Thanks for your interest here.
MONAI metrics support different reduction methods during aggregation:

You can select the expected method.

Thanks.
