Self-supervised Monocular Depth Estimation for All Day Images using Domain Separation

2 code implementations ICCV 2021 Lina Liu, Xibin Song, Mengmeng Wang, Yong liu, Liangjun Zhang

Meanwhile, to guarantee that the day and night images contain the same information, the domain-separated network takes the day-time images and corresponding night-time images (generated by GAN) as input, and the private and invariant feature extractors are learned by orthogonality and similarity loss, where the domain gap can be alleviated, thus better depth maps can be expected.
