Abstract
In this chapter, we focus on the theoretical basis of the method of tracking a person's head, based on the construction of its geometric texture patterns, and finding the parameters of its movement between pairs of consecutive video frames. The task of tracking the position of geometric head model is formulated as the problem of determining the parameters of the model (translation and rotation) so that the projection of a 3D model of the head on the video frame coincides with the real image of the head in this picture. To solve this problem, we use an efficient algorithm for infrared imaging. The application of the expressions is obtained during movement of the head as a three-dimensional body with six degrees of freedom and the use of perspective projection and for avatars modeling by Prof Vardan Mkrttchian last publications in IGI Global 2011-2015.
