Eigenface-based 的人脸识别系统的鲁棒性
WebEigenface (and other appearance-based) approaches must be coupled with feature- or shape-based approaches to recognition, possibly including 3D data and models, in order … WebMay 1, 2024 · Face recognition is the process of taking a face in an image and actually identifying who the face belongs to. Face recognition is thus a form of person identification. Early face recognition systems relied on an early version of facial landmarks extracted from images, such as the relative position and size of the eyes, nose, cheekbone, and jaw ...
