摘要:

数字图像篡改技术的快速发展给内容验证带来了严峻挑战,stable diffusion(稳定扩散)、mid-journey等模型生成的合成图像高度逼真,足以骗过人类感知。本研究开发并评估了专门用于检测这类篡改图像的卷积神经网络(CNNs)。研究对三种复杂度递增的CNN架构开展了对比分析,评估它们在各类人脸图像篡改场景下的分类与篡改定位能力。研究系统引入了正则化与优化技术,以提升特征提取效果与模型性能。结果显示,所提出的模型在区分篡改图像与真实图像时准确率最高可达76%,性能优于传统方法。本研究不仅彰显了CNN在提升数字媒体验证工具鲁棒性方面的潜力,还为低计算环境下有效的架构适配与训练策略提供了思路。未来工作将基于这些发现,拓展架构以应对更多样的篡改技术,并整合多模态数据进一步提升检测能力。

英文摘要:

The rapid evolution of digital image manipulation techniques poses significant challenges for content verification, with models such as stable diffusion and mid-journey producing highly realistic, yet synthetic, images that can deceive human perception. This research develops and evaluates convolutional neural networks (CNNs) specifically tailored for the detection of these manipulated images. The study implements a comparative analysis of three progressively complex CNN architectures, assessing their ability to classify and localize manipulations across various facial image modifications. Regularization and optimization techniques were systematically incorporated to improve feature extraction and performance. The results indicate that the proposed models achieve an accuracy of up to 76\% in distinguishing manipulated images from genuine ones, surpassing traditional approaches. This research not only highlights the potential of CNNs in enhancing the robustness of digital media verification tools, but also provides insights into effective architectural adaptations and training strategies for low-computation environments. Future work will build on these findings by extending the architectures to handle more diverse manipulation techniques and integrating multi-modal data for improved detection capabilities.
