Why there are strange mask parts in the annotation?

For example, the person part is annotated with white color, but there are parts annotated person part between the face and eyebrow, and also between the face and lip. This may confuse the model

Hello!

We excluded face pixels from the "person" class to store the whole mask in single-channel form. To obtain a continuity mask for the "person" class, you need to set all pixels not related to the background to 1. In the paper, we trained models for face parsing and portrait segmentation tasks separately, so as not to confuse the model.
