Unverified绝大多数深度伪造检测模型在'干净'的生成器输出上训练和评估，但现实中图片到达检测系统前已经历JPEG重压缩、分辨率缩放、色彩空间转换、EXIF剥离等多轮变换79% similarUnverified深度伪造检测器通常依赖像素级微小异常、高频噪声模式或压缩伪影中的生成器特征，而平台处理会系统性地破坏或覆盖这些信号75% similarUnverified顶级深度伪造检测模型碰到经过压缩的视频时识别率会大幅下降74% similarUnverified在深度伪造检测的生产环境中真实图像与伪造图像比例可能高达1000:1甚至更高，极端不平衡下AUC对长尾失败几乎没有区分度73% similarUnverifiedAfter superimposing tiny perturbations that are nearly invisible to the human eye onto an image correctly classified by a neural network, the model output will produce an error with extremely high confidence.69% similar
