2021 arXiv   pre-print
Inspired by this, we propose to reduce the intrinsic style bias of CNNs to close the gap between domains.  ...  Our Style-Agnostic Networks (SagNets) disentangle style encodings from class categories to prevent style biased predictions and focus more on the contents.  ...  Our method is orthogonal to the majority of existing domain adaptation and generalization techniques that utilize Figure 1 : Our Style-Agnostic Network (SagNet) reduces style bias to reduce domain gap  ...

It can explicitly divide the learnable feature into camera-specific and camera-agnostic parts, reducing the influence of different cameras.  ...  However, most methods ignore the intra-class gap caused by camera style variance, and some methods are relatively complex and indirect although they try to solve the negative impact of the camera style  ...  As for the UDA methods, some of them use GAN [14, 15] for style transfer to narrow the gap between the source domain and target domain.  ...
