Recent Monte Carlo denoising methods have achieved impressive progress in generating visually compelling images, which accelerate path-tracing based rendering. However, most of them rely on strong supervision, resulting in a high computational burden for creating paired data and potential overfitting issues. Instead, we present an unsupervised approach based on contrastive disentanglement representation. Specifically, we introduce disentanglement representation combined with cycle-consistency and adversarial loss to factorize noise and content features from a noisy input. Besides, we enforce contrastive learning on abundant samples generated in the backbone to regularize the extracted content distribution, reducing noise features. Moreover, we introduce a multi-scale modulation to refine the representation of auxiliary features, providing better denoising guidance. Experimental results demonstrate that our approach performs favor-ably against existing state-of-the-art unsupervised methods and generates comparable results against supervised models while requiring less inference time.
