How to Develop overlapping multi labeled segmentation.

[erenkal]

I have 20 labels some of them are overlapping. Data in 4D nifti format [x][y][z][ labels ] labels are 1 and 0 in a list.
How should I use the monai features ?
Should I train a model with 20 input channels ?

yes, you can save it into shape [x, y, z, 20], along the last dimension are binary vectors, and use a 20-channel model. just in the segmentation loss/metric functions set to_onehot_y=False, and softmax=False, sigmoid=True (to avoid the assumption of mutually exclusive labels).

How should I create dataset and dataloader ?
Are there any examples?
