Abstract
Image denoising is often used as a preprocessing step in computer
vision tasks, which can help improve the accuracy of image processing models.
Due to the imperfection of imaging systems, transmission media and recording
equipment, digital images are often contaminated with various noises during
their formation, which troubles the visual effects and even hinders people’s
normal recognition. The pollution of noise directly affects the processing of
image edge detection, feature extraction, pattern recognition, etc., making it
difficult for people to break through the bottleneck by modifying the model.
Many traditional filtering methods have shown poor performance since they do
not have optimal expression and adaptation for specific images. Meanwhile, deep
learning technology opens up new possibilities for image denoising. In this paper,
we propose a novel neural network which is based on generative adversarial
networks for image denoising. Inspired by U-net, our method employs a novel
symmetrical encoder-decoder based generator network. The encoder adopts
convolutional neural networks to extract features, while the decoder outputs the
noise in the images by deconvolutional neural networks. Specially, shortcuts are
added between designated layers, which can preserve image texture details and
prevent gradient explosions. Besides, in order to improve the training stability of
the model, we add Wasserstein distance in loss function as an optimization. We
use the peak signal-to-noise ratio (PSNR) to evaluate our model and we can
prove the effectiveness of it with experimental results. When compared to the
state-of-the-art approaches, our method presents competitive performance.
