One of the challenges in automatic face recognition is to achieve temporal invariance. In other words, the goal is to come up with a representation and matching scheme that is robust to changes due to facial aging. Facial aging is a complex process that affects both the 3D shape of the face and its texture (e.g., wrinkles). These shape and texture changes degrade the performance of automatic face recognition systems. However, facial aging has not received substantial attention compared to other facial variations due to pose, lighting, and expression. We propose a 3D aging modeling technique and show how it can be used to compensate for the age variations to improve the face recognition performance. The aging modeling technique adapts view-invariant 3D face models to the given 2D face aging database. The proposed approach is evaluated on three different databases (i.g., FG-NET, MORPH, and BROWNS) using FaceVACS, a state-of-the-art commercial face recognition engine.
自动人脸识别面临的挑战之一是实现时间不变性。换句话说,目标是提出一种表示和匹配方案,使其能够抵抗由于面部老化引起的变化。面部老化是一个复杂的过程,它会影响面部的 3D 形状和纹理(例如皱纹)。这些形状和纹理的变化会降低自动人脸识别系统的性能。然而,与由于姿势、光照和表情等其他面部变化相比,面部老化并没有受到太多关注。我们提出了一种 3D 老化建模技术,并展示了如何使用它来补偿年龄变化,以提高人脸识别性能。该老化建模技术使视图不变的 3D 人脸模型适应给定的 2D 人脸老化数据库。所提出的方法使用最先进的商用人脸识别引擎 FaceVACS 在三个不同的数据库(即 FG-NET、MORPH 和 BROWNS)上进行了评估。
