This repository provides codes that we use to study the mutual influence between image denoising and high-level vision tasks.

(1) We present an image denoising network which achieves state-of-the-art image denoising performance.

(2) We propose a deep network solution that cascades two modules for image denoising and various high-level tasks, respectively, and demonstrate that the proposed architecture not only yields superior image denoising results preserving fine details, but also overcomes the performance degradation of different high-level vision tasks, such as image classification and semantic segmentation, due to image noise.

This code repository is built on top of DeepLab v2.

• Run get_models.sh to download models used in our work.

• cd exper
• Run main_train_denoise.sh to train the denoising network seperately.
• Run main_train_cls.sh to jointly train the cascade of the denoising network and the network for image classification.
• Run main_train_seg.sh to jointly train the cascade of the denoising network and the entwork for semantic segmentation.

• cd exper
• Run main_test_cls.sh to test the resulting model for image classification.
• Run main_test_seg.sh to test the resulting model for semantic segmentation.
• Run main_test_denoise.sh to generate denoised results.
