Segmentation-aware Image Denoising Without Knowing True Segmentation

Sicheng Wang, Bihan Wen, Junru Wu, Dacheng Tao, Zhangyang Wang

we propose a segmentation-aware image denoising model dubbed U-SAID, which does not need any ground-truth segmentation map in training, and thus can be applied to any image dataset directly. We demonstrate the U-SAID generates denoised image has:

• better visual quality;
  
• stronger robustness for subsequent semantic segmentation tasks.
  

We also manifest U-SAID's superior generalizability in three folds:

• denoising unseen types of images;
  
• pre-processing unseen noisy images for segmentation;
  
• pre-processing unseen images for unseen high-level tasks.
  

U-SAID: Network architecture. The USA module is composed of a feature embedding sub-network for transforming the denoised image to a feature space, followed by an unsupervised segmentation sub-network that projects the feature to a segmentation map and calculates its pixel-wise uncertainty.
