Confused about the number of classes when segmenting with Mask2Former

Hello,
As I see in the file InternImage/segmentation/mmseg_custom/models/decode_heads /mask2former_head.py
, there is this line:
self.cls_embed = nn.Linear(feat_channels, self.num_classes + 1)
I am wondering why the +1
is there. As far as I've understood, it's for the background class. But what if my dataset already has a background class? Should I ignore it in the ToMask
transform?
