Nighttime surveillance suffers from degradation due to poor illumination and arduous human annotations.
... argue that the ultimate solution for nighttime surveillance is night-to-day translation, or Night2Day, which aims to translate a surveillance scene from nighttime to the daytime while maintaining semantic consistency.
To achieve this, this paper presents a Disentangled Contrastive (DiCo) learning method.
... propose a learnable physical prior, i.e., the color invariant, which provides a stable perception of a highly dynamic night environment and can be incorporated into the learning pipeline of neural networks.
... develop a disentangled representation, which is an auxiliary pretext task that separates surveillance scenes into the foreground and background ... can extract the semantics without supervision and boost ... achieve instance-aware translation.
... demonstrate that ... method outperforms existing works significantly ...
