Method for Increasing The Accuracy of Tracking The Center of Attention of The Gaze

Defending against threats in today's world requires the latest technology. One of the promising methods for solving problems is biometric. The algorithm of operation of optoelectronic biometric security systems, the task of which is to assess the emotional response of a person to a specific test object, must include a marker by which the system will distinguish a predetermined emotional response of a person. Pupillometry and tracking can be successfully used in such systems. Biometric systems aimed at searching for certain signs of a psychophysical state with the help of pupils must be able to interpret them correctly. The decryption process is very difficult because the size of the pupil depends on many factors. Thus, one of the most important tasks, the solution of which is a determining factor in whether the developed biometric system will work, is to explain each plot of the pupil. In addition, the task of accurately contouring and building a spotlight track comes to the fore. Our research aims to improve the accuracy of attention tracking without using infrared lighting.
