UCDFormer: Unsupervised Change Detection Using a Transformer-driven Image Translation

1 code implementation2 Aug 2023 Qingsong Xu, Yilei Shi, Jianhua Guo, Chaojun Ouyang, Xiao Xiang Zhu

Specifically, a transformer-driven image translation composed of a light-weight transformer and a domain-specific affinity weight is first proposed to mitigate domain shift between two images with real-time efficiency.
