Calculating the angle of human movement direction by studying the parameters of a gait using video sequences

Authors: Kataev M. Yu., Rudova E. V.

Annotation: The process of identifying human movements using technical vision methods attracts many researchers to this topic, as it could be applied in medicine, sports, and protection; consequently it initiated the appearance of many software and hardware applications. These applications range from simple gesture recognition to a complex understanding of human behavior in surveillance systems. This leads to a serious development of methods related to the representation and recognition of human movements. However, in the practical use of these applications, there are inaccuracies in the extraction of information associated with a change in the direction of movement of a person relative to the axis of sight of the camera. The article discusses an approach that allows building applications for the recognition of human movements, taking into account the different directions of its movement relative to the camera.
