Due to the exponential growth of high-quality fake photos on social media and the Internet, it is critical to develop robust forgery detection tools. Traditional picture- and video-editing techniques include copying areas of the image, referred to as the copy-move approach. The standard image processing methods physically search for patterns relevant to the duplicated material, restricting the usage in enormous data categorization. On the contrary, while deep learning (DL) models have exhibited improved performance, they have significant generalization concerns because of their high reliance on training datasets and the requirement for good hyperparameter selection. With this in mind, this article provides an automated deep learning-based fusion model for detecting and localizing copy-move forgeries (DLFM-CMDFC). The proposed DLFM-CMDFC technique combines models of generative adversarial networks (GANs) and densely connected networks (DenseNets). The two outputs are combined in the DLFM-CMDFC technique to create a layer for encoding the input vectors with the initial layer of an extreme learning machine (ELM) classifier. Additionally, the ELM model's weight and bias values are optimally adjusted using the artificial fish swarm algorithm (AFSA). The networks' outputs are supplied into the merger unit as input. Finally, a faked image is used to identify the difference between the input and target areas. Two benchmark datasets are used to validate the proposed model's performance. The experimental results established the proposed model's superiority over recently developed approaches.
由于社交媒体和互联网上高质量假照片的指数级增长,开发强大的伪造检测工具至关重要。传统的图片和视频编辑技术包括复制图像的区域,称为复制-移动方法。标准图像处理方法从物理上搜索与重复材料相关的模式,限制了在大规模数据分类中的使用。相反,虽然深度学习 (DL) 模型表现出了改进的性能,但由于它们高度依赖训练数据集和对良好超参数选择的要求,因此存在重大的泛化问题。考虑到这一点,本文提供了一种用于检测和定位复制-移动伪造的自动化深度学习融合模型 (DLFM-CMDFC)。所提出的 DLFM-CMDFC 技术结合了生成对抗网络 (GAN) 和密集连接网络 (DenseNets) 的模型。在 DLFM-CMDFC 技术中,将两个输出结合起来,创建一个使用极限学习机 (ELM) 分类器初始层对输入向量进行编码的层。此外,使用人工鱼群算法 (AFSA) 对 ELM 模型的权重和偏差值进行最优调整。网络的输出作为输入提供给合并单元。最后,使用伪造图像来识别输入区域和目标区域之间的差异。使用两个基准数据集来验证所提出模型的性能。实验结果证明了所提出模型优于最近开发的方法。
