Lables for each pixel is identified by a number . So if you have a
binary case n_classes should be set to 2 and
labels should be 0 and 1 for each class and pixel.
In the case of multiclass just set n_classes to the number of classes you have and the try to produce the labels
In the case of multiclass just set n_classes to the number of classes
you have and the try to produce the labels
by pixels set from 0 , 1 ,2 .., n_classes-1.
The labels format should be png.
If you have an image label for binary case it should look like this:
Label: [ [[1 0 0 1], [1 0 0 1] ,[1 0 0 1]], [[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ,[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ]
this means that you have an image by 3*4*3 and pixel[0,0] belongs to class 1 and pixel[0,1] to class 0.
Label: [ [[1 0 0 1], [1 0 0 1] ,[1 0 0 1]],
[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ,
[[1 0 0 1], [1 0 0 1] ,[1 0 0 1]] ]
This means that you have an image by 3*4*3 and pixel[0,0] belongs
to class 1 and pixel[0,1] to class 0.

if you want to train your model with patches, the height and width of

batchs (how many patches should be seen by model by each iteration).
In the case that model should see the image once, like page extraction, the patches should be set to false.
