Algorithms for recognizing emotions by expressing a person’s face are of significant commercial value and are kept secret. In Silver Logic Labs claim that brought the technology to perfection – to work they need only a digital camera with a sufficiently high resolution. It scans small movements of facial muscles at a frequency of several times per second, which allows not only to recognize the momentary emotion, but also to track the change in the mood of the viewer over time.
Curiously, the hardware requirements for this system of emotion recognition are very modest. For example, she is able to work with police cameras, which will quickly give an answer – whether the suspect bluffs when he says that he is unarmed? And if you adapt it to a video surveillance system in a hospital or nursing home, you can foresee the onset of an attack in the patient, when the person is just making up involuntary grimaces of minor pain.
Applying technology to surveillance cameras for the crowd, you can try to calculate a suicide, a suicide bomber with a bomb or a drug addict under the influence of substances. The teacher will understand how students perceive the lesson, the deputy will read the thoughts of the voters, the lovers will understand their feelings, and the diplomats will receive a formidable weapon for negotiations. By the way, this is by no means a fantasy – developers report that the system is already almost unmistakably recognizes people who are under the influence of narcotic substances.
