Abstract
Image denoising has always been one of the research hotspots in the field of image processing, which aims to remove the noise from the imaging device or external noise environment and other interfering factors in the image to restore the noisy image to the original clean and noise-free image. Mature algorithms and machine learning techniques have been developed previously for different application situations and specific computer vision works. Image denoising based on deep learning can adaptively learn image content and is suitable for image denoising tasks in high-noise environments. This paper builds a model based on the representative image denoising algorithm DnCNN, and discusses the performance difference with other denoising algorithms. All the results show the new methods are usually more efficient than traditional ones which can process pictures that are under more complex conditions.
