WebMar 25, 2014 · As far as I know there is not a standard rule for the threshold selection in face recognition. Since you seem to have a training set of images, you can try to select a threshold based on a biometric performance metric, e.g. the false acceptance rate (FAR) and false match rate (FMR). WebMar 29, 2024 · Basic Idea. Eigenfaces is a representation learning method in computer vision focusing on facial images. The goal of the method is to represent an image that depicts the face of a person as a linear combination of a set of basic images that are called eigenfaces. Suppose all images representing a human face lie in a manifold in .
