论文摘要
2022年俄罗斯对乌克兰的入侵在两个方面进行了战斗：一场残酷的地面战争和一场旨在掩盖和证明俄罗斯行动正当的偶然的虚假宣传运动。这项运动至少包括一个据称显示乌克兰总统Zelenskyy承认失败和投降的一个示例。为了期待这种形式的未来攻击，我们描述了一种面部和手势行为模型，该模型捕获了Zelenskyy的口语风格的独特特征。经过八个多个小时的真实视频的培训，我们表明，这种行为模型可以将Zelenskyy与Deep-Fake Imposters区分开。该模型可以在将真实的角色与假货区分开来扮演重要角色，尤其是在战争的雾中 - 尤其是在战争中。
The 2022 Russian invasion of Ukraine is being fought on two fronts: a brutal ground war and a duplicitous disinformation campaign designed to conceal and justify Russia's actions. This campaign includes at least one example of a deep-fake video purportedly showing Ukrainian President Zelenskyy admitting defeat and surrendering. In anticipation of future attacks of this form, we describe a facial and gestural behavioral model that captures distinctive characteristics of Zelenskyy's speaking style. Trained on over eight hours of authentic video from four different settings, we show that this behavioral model can distinguish Zelenskyy from deep-fake imposters.This model can play an important role -- particularly during the fog of war -- in distinguishing the real from the fake.
