Traditional image denoising methods are typically based on mathematical models and signal processing techniques, such as filtering and wavelet transform. However, these methods have certain limitations in handling complex noise and preserving image details. In recent years, the rapid development of deep learning technology has provided new solutions for image denoising. Deep learning models, particularly convolutional neural networks (CNNs), can more effectively remove noise and preserve image details by automatically learning image features and noise patterns.This paper aims to study deep learning-based image denoising methods by constructing and training deep learning models to achieve high-quality denoising of noisy images. The research content includes the following aspects: first, introducing the background and significance of image denoising, and analyzing the advantages and disadvantages of traditional denoising methods; second, elaborating on the basic principles and common models of deep learning, particularly the structure and training methods of convolutional neural networks; then, designing and implementing a deep learning-based image denoising model, including dataset preparation, model architecture design, loss function selection, and optimization of training strategies; finally, validating the effectiveness of the proposed method through experiments and conducting comparative analysis with traditional denoising methods.The experimental results show that deep learning-based image denoising methods outperform traditional methods in terms of noise removal and detail preservation. Deep learning models can adaptively learn noise features and maintain good denoising performance under different noise levels. Additionally, this paper explores the model's performance under different types of noise, verifying its robustness and generalization ability.**Keywords:** Image denoising; Deep learning; Convolutional neural network; Noise removal; Image restoration# 目 录## 1 绪论1.1 研究背景与意义 ...... 1 1.2 国内外研究现状 ...... 2 1.3 研究内容与结构安排 ...... 3 ## 2 图像去噪相关理论2.1 图像噪声模型 ...... 5 2.2 传统图像去噪方法 ...... 6 2.3 深度学习基础 ...... 8 ## 3 基于深度学习的图像去噪模型设计3.1 数据集准备与预处理 ...... 11 3.2 模型架构设计 ...... 12 3.3 损失函数与优化算法 ...... 14 ## 4 实验设计与结果分析4.1 实验环境与参数设置 ...... 16 4.2 实验结果与分析 ...... 17 4.3 与传统方法的对比 ...... 19 ## 5 结论与展望5.1 研究总结 ...... 21 5.2 未来工作展望 ...... 22 参考文献 ...... 23 致 谢 ...... 25 兰州交通大学本科毕业论文1 绪论1.1 研究背景与意义图像去噪是图像处理领域中的一个基础且重要的研究方向,其目标是从受到噪声污染的图像中恢复出原始清晰的图像。噪声可能来源于图像采集、传输或存储过程中的各种因素,如传感器噪声
