Class-Aware Fully-Convolutional Gaussian and Poisson Denoising

20 Aug 2018  ·  Tal Remez, Or Litany, Raja Giryes, Alex M. Bronstein ·

We propose a fully-convolutional neural-network architecture for image denoising which is simple yet powerful. Its structure allows to exploit the gradual nature of the denoising process, in which shallow layers handle local noise statistics, while deeper layers recover edges and enhance textures. Our method advances the state-of-the-art when trained for different noise levels and distributions (both Gaussian and Poisson). In addition, we show that making the denoiser class-aware by exploiting semantic class information boosts performance, enhances textures and reduces artifacts.
