Development of a Database of Human-s Phenotype Images for Establishment and Researching of Methods to Determine the Stress State and the Functional Status of the Person

At the present time, as a result of the complexity of professional activities, it is especially important to develop methods for evaluating individual psychophysiological, intellectual and other qualities of a specialist, as well as methods for assessing its current state (including determining the presence and degree of stress). The most promising methods of assessing functional status are the methods of human-s phenotype-s features images analysis - the features of the iris and papillary patterns of human fingers. Determination of person-s stress can be made by analyzing facial images and the selection of facial patterns on them, because the various forms of stress are accompanied by various motoric activity, and in particular facial expressions.

To investigate the possibility of developing methods for determine the state of stress and functional status by the hu-man-s phenotype images, for development, testing and debugging of the algorithms an image databases of human phenotypes are required, which are currently lacking.

For the first time comprehensive database of the human-s phenotype images that includes an image of 112 people of different gender and race at the age of 17 to 33 years is formed. The database contains:

rolled fingerprint images of 10 fingers with a resolution of 500 dpi;

images of left and right iris with a resolution of at least 1000x1000 pixel;

face video with a resolution of 1920 x 1080 pixel in a stress state with duration of 5-10 minutes and in the basic emotion-al states (anger, disgust, fear, joy, sadness, surprise) with duration of 2-10s;

physiological parameters - rhythmocardiography and heart rate variability;

performance parameters - number of errors and the time of the test execution.

To register a fingerprint image we used rolled inkless fingerprint scanner, to register iris images - a digital SLR camera with a macro lens and ring illuminator. To register a face video we used digital SLR camera with video recording capabilities. Video recording was carried out in a room with controlled conditions of registration to ensure sufficient levels of illumination, absence of irregularity and asymmetry of the light. In order to reproduce the stress state the simulation of operator's activity software is developed, which is a set of test items: a black and red Schulte-s tables and reaction to a moving object with color choices under time pressure.

This database can be used for development and testing of algorithms for determining the functional state and func-tional status of the individual, occupational selection, assessment of the operators of complex automated systems, evaluation of emotional state.
