Unsupervised person re-identification (re-ID) aims to learn identity information from a source domain (e.g. one surveillance system) and apply it to a target domain (e.g. a different surveillance system). This is challenging due to occlusion, viewpoint, and illumination variations between the different domains (i.e. systems). In this paper, we propose a neural network architecture, known as Synthetic Model Bank (SMB), to address illumination variation in unsupervised person re-ID. The basic idea of SMB is to use synthetic data for training different re-ID models for different illumination conditions. From our experiments, the proposed SMB outperforms other synthetic augmentation methods on several re-ID benchmarks.

Person re-identification (re-ID) has wide applications in surveillance and security. It is also challenging due to viewpoint, occlusion and illumination variations across different cameras. One solution to unsupervised person re-ID problems is synthetic data augmentation. Generative neural networks have been used to translate images from the source domain into the target domain. In this paper, we introduce a new virtual-human image dataset that can be used as the source domain for person re-ID. This new dataset has images labeled by person identity, background, viewpoint and illumination intensity. We also explore GAN-based and Diffusion-based generative methods for unpaired image-to-image translation and provide qualitative and quantitative evaluation for the synthetic results.
