摘要:

提出了一种基于图像边缘区域特征的人脸篡改检测方法。目前的人脸合成方法大多数都包含了减少颜色不协调的处理,但是在边缘区域会破坏自然指纹。另外,在非面部背景区域中不进行这些颜色校正处理。我们还观察到,合成过程不考虑出现在时域中的图像的自然属性。考虑到这些意见,我们提出了一个面部法医框架,利用像素级的颜色特征出现在整个图像的边缘区域。此外,我们的框架包括一个3D-CNN分类模型,该模型在空间和时间上解释提取的颜色特征。与其他现有的研究不同,我们通过考虑从一个视频中的多个帧中提取的所有特征来进行真实性确定。通过广泛的实验,包括真实世界的场景来评估广义检测能力,我们表明,我们的框架在准确性和鲁棒性方面优于最先进的面部操作检测技术。

英文摘要:

This paper presents a generalized and robust face manipulation detection method based on the edge region features appearing in images. Most contemporary face synthesis processes include color awkwardness reduction but damage the natural fingerprint in the edge region. In addition, these color correction processes do not proceed in the non-face background region. We also observe that the synthesis process does not consider the natural properties of the image appearing in the time domain. Considering these observations, we propose a facial forensic framework that utilizes pixel-level color features appearing in the edge region of the whole image. Furthermore, our framework includes a 3D-CNN classification model that interprets the extracted color features spatially and temporally. Unlike other existing studies, we conduct authenticity determination by considering all features extracted from multiple frames within one video. Through extensive experiments, including real-world scenarios to evaluate generalized detection ability, we show that our framework outperforms state-of-the-art facial manipulation detection technologies in terms of accuracy and robustness.
