London has on average 100 cameras per person. More and more buildings and street corners where you live are getting littered with the new symbol of the 21st century – the security camera. This isn’t our concern however. I’ve just finished skimming through this PDF document and i’m speechless. You’ve heard about the biometric scanning cameras they now have installed in basically everything to do with public international transport, but did you know they other sciences behind it? Specifically their ability to figure out your psychological profile – not only your facial expression!
The face plays a crucial role in human social cognition. Facial expressions are important signals of internal states – emotions and intentions. Humans also see in the face signals of internal qualities that are more stable over time, like attractiveness as a mate or dominance , etc.
“There can be little doubt that the face plays a crucial part in our everyday assessment of our fellows. Not only does it enable us to identify transient emotions – flashes of pleasure and rage, disappointment and hatred – it can also help us to make useful judgments about more durable and lasting qualities of personality and character”. Judging personality from face comes from ancient times to nowadays. The belief that the face reveals information about underlying character cuts across national, cultural and geographical boundaries. Several classical Greek and Roman scholars, including Plato and Aristotle, argued that faces contain clues about people’s underlying personalities and dispositions. For over 2500 years many notable philosophers, historians and physicians openly supported the idea that a person’s disposition is reflected in their face.
The nature of computer vision causes the fact that not only computer science researchers are interested in it, but neuroscientists and psychologists, too. One of the main interests for psychology is identification of person’s psychological traits and personality types which can be accomplished by different means of psychological testing: questionnaires, interviews, direct observations, etc. Though that is a general tendency of people to read character into a person’s physical form, especially face. In relation to psychological characteristics recognition, face provides researchers and psychologists with instrument of obtaining information about personality and psychological traits that would be much more objective than questionnaires and neuropsychological tests and could be obtained remotely using person’s facial portrait, with no need for personal involvement. The paper describes approaches to psychological characteristics recognition from facial image such as physiognomy, phase facial portrait, ophthalmogeometry, and explains the need in automating it.
The paper represents general idea that face provides researchers and psychologists with objective instrument of obtaining information about personality and psychological traits. An up-to-date survey of approaches and methods in psychological characteristics recognition from facial image is provided. In perspective new research task of automating procedures in applications of psychological characteristics recognition from face should be explored. Various approaches and methods developed within face recognition, facial expression recognition, face retrieval, face modeling and animation may be applied and adjusted for recognition of psychological characteristics from face. Undeniably, such automated system of psychological characteristics recognition from face will get countless psychological, educational, business applications. It may be used also as part of medical systems: 1) patient’s psychological state and traits influence the process of medical treatment, and it should be taken into consideration and researched; 2) patient’s psychological characteristics should be taken into account to reflect and construct the psychosomatic model of disease in the environment, which includes biological, psychological, and social factors.
