Annotation: Assessing the position of the center of mass (CM) of a human body picture is a very important problem in the analysis of human movement (gait). There are various methods to evaluate a person’s gait. Nevertheless, the use of video images for gait analysis has many advantages over other methods, due to its accessibility and ease of perception of the results. In this article, the authors propose a technique to isolate patterns of human movement based on the assessment of the position of the CM when using digital video cameras. Although there are many well known image-processing algorithms, their sequence and ability to consider the specifics of detecting a moving person allows to obtain a stable and accurate methods to process video images. The pattern of human movement based on an assessment of gait parameters is formed. Such a characteristic enables obtaining a suitable basis to design a system for human’s gait analysis at a specific time and to compare it and use it the data in subsequent measurements.
