OpenFace

OpenFace is an open-source software tool that analyzes images or videos to detect and interpret human facial features and expressions. It identifies key points on the face, such as eyes, nose, and mouth, enabling it to recognize emotions, verify identity, or track head movements. Think of it as a digital "face reader" that helps computers understand and respond to human facial cues, useful in applications like security, emotion research, or human-computer interaction. Its accessibility and flexibility make it a popular choice for developers and researchers working with facial analysis.
