Practice experts use mathematical methods to objects of portrait expertise

Abstract

Uniform application of forensic portrait examination techniques is the key to the correct evaluation of the results of the study. Since this problem is quite global, we will focus only on some of its aspects related to the determination of absolute mathematical values for the photo and video frames. The use of numerical values of the objects of study gives the results of the examination a greater degree of objectivity, and hence the reliability of the findings. If we talk about the methods of identification of the person on the grounds of appearance, in the developing technological society, the use of quantitative methods has significant potential, since the comparison of only the characteristics of the elements of the person is not enough to formulate a conclusion. However, we should not forget that each technique is calculated under well-known or specific conditions, violating which, the expert receives inadequate and sometimes erroneous results. It appears that the solving of urgent tasks of face identification can be found through the joint efforts of experts from different areas through the improvement of methodological support based on the principles developed by the judicial expertology
