FACE4
FACE4 is an open, modular software framework for facial analysis and recognition. The acronym stands for Four-Component Facial Analysis and Characterization Engine, reflecting its architecture built around four core capabilities: face detection, facial landmark localization, attribute and expression classification, and identity verification. It is designed for researchers and developers in computer vision, human-computer interaction, and biometric applications.
