As complexity and capabilities of Artificial Intelligence technologies increase, so does its potential for misuse. Deepfake videos are an example. They are
Introduction 这篇论文提出了一种完全无监督的Deepfake视频检测方法,采用增强对比学习来检测深度伪造视频。该工作主要解决传统的监督检测方法需要大量标记数据进行训练,但当标记数据不足或被恶意篡改时,检测效果可能不可靠。 为了解决这一问题,作者设计了一个伪标签生成器,通过传统手工特征(VAF)对样本进行初步聚类并生成伪...
While the abuse of deepfake technology has caused serious concerns recently, how to detect deepfake videos is still a challenge due to the high photo-realistic synthesis of each frame. Existing image-level approaches often focus on single frame and ignore the spatiotemporal cues hidden in deepfake...
Malicious individuals misuse deepfake technologies to spread false information, such as fake images, videos, and audio. The development of convincing fake content threatens politics, security, and privacy. The majority of deepfake video detection methods are data-driven. This survey paper aims to ...
这篇文章从一个新的角度出发,不同于以往的直接对单个视频进行检测,而是更贴合实际。例如:当一个名人需要来证实一段视频是deepfake自己的脸,只需要她提供自己真实的一段视频来与需要鉴定的视频进行比较即可判定出来。比较符合当前的现实需求。 Motivation 当前的deepfake检测技术很多在面部重建操作上的检测效果不太好,所以...

With the rise of AI-enabled Real-Time Deepfakes (RTDFs), the integrity of online video interactions has become a growing concern. RTDFs have now made it feasible to replace an imposter's face with their victim in live video interactions. Such advancement in deepfakes also coaxes detection ...
