Continual coarse-to-fine domain adaptation in semantic segmentation

作者:

Highlights:

• We define a novel task combining coarse-to-fine learning and domain adaptation.

• Coarse-to-fine knowledge distillation transfers knowledge acquired on coarse classes.

• Coarse-to-fine unbiased weight initialization rule accounts for hierarchical splits.

• Maximum squares minimization addresses domain shift.

• We design and evaluate on two synthetic-to-real benchmarks in the driving scenario.
