Orthogonal Decoupling Contrastive Regularization for Unpaired Image Dehazing

The proposed Orthogonal Decoupling Contrastive Regularization (ODCR) method aims to decouple image features into haze-related and haze-unrelated components, and then maximize the mutual information between the corresponding components of the dehazing result and the clear/hazy input images, thereby achieving effective unpaired image dehazing.
