Core Concepts
Facial expression recognition models can be misled by subtle adversarial attacks that preserve the surface structure of 3D faces.
Abstract
이 논문은 3D 얼굴 표정 인식 모델에 대한 표면 기반 적대적 포인트 클라우드 공격인 ϵ-Mesh Attack에 대해 소개합니다. 이 공격은 3D 얼굴의 표면 구조를 보존하면서 모델을 오도할 수 있는 섬세한 적대적 공격을 제공합니다. 논문에서는 ϵ-Mesh Attack의 작동 방식, 실험 결과 및 잠재적인 응용 분야에 대해 상세히 설명합니다.
