摘要

深度卷积神经网络的提出引发了图像处理算法的一系列突破。但是,使用更深入的网络并不总是有帮助,训练它们的巨大障碍是逐渐消失的梯度、大量增长的参数和过长的时间。本文提出了一种基于深度残差网络的图像混合噪声去除算法。通过全局残差学习与局部残差学习,有效地解决了梯度消失与网络参数的增长,提升了模型对图像特征的选择与提取能力,减少了训练时间。实验结果表明,深度残差网络在图像混合噪声去除中效果显著,本文提出的算法得到的去噪图像更好地恢复图像的原始结构,信息丰富,对比度高,鲁棒性强,并且可以更好地保持图像的细节。

Abstract

The introduction of deep convolutional neural networks has resulted in a series of breakthroughs in image processing algorithms. However, the use of deeper networks is not always helpful, and the great difficulty in training them lies in the gradual disappearance of gradients, the large increase in parameters, and the lengthy timeframe. This paper proposes an image mixing noise removal algorithm based on a deep residual network. Through global and local residual learning, the gradient disappearance and the increase in network parameters are effectively solved, which improves the model's ability to select and extract image features and reduce training time. The results of the experiment show that the deep residual network is effective in image mixed noise removal. The denoised image obtained with the proposed algorithm can better restore the original structure of the image, has richer information, higher contrast, a strong robustness, and details of the image are maintained more successfully.
