- Preprocesamiento: The captured image undergoes preprocessing to enhance quality, which may include adjustments for lighting, orientation, and background.
- Extracción de características: The system identifies and extracts distinctive features from the face, which can include geometric properties and texture patterns.
- Comparación facial: The extracted features are then compared against a database of known faces using algorithms que miden la similitud.
- Toma de Decisiones: Based on the comparison, the system either recognizes the individual or indicates a lack of match.

However, it also raises significant ethical concerns related to privacy and the potential for misuse, leading to ongoing discussions regarding regulations and standards in its deployment.
