Facial analysis is the study of facial features and expressions to understand emotions, personality traits, and even health conditions. It involves examining aspects such as the shape of the face, the position of the eyes, and the movement of the mouth. This technique is often used in fields like psychology, security, and marketing to gain insights into human behavior. In recent years, advancements in technology have led to the development of software that can analyze faces using algorithms. These tools can identify patterns and make predictions based on data, contributing to areas like artificial intelligence and facial recognition systems.
