Dimensional unit as an aid in students identification

The aim of this paper is the proposal of the solution that is to enable identification of students based on their height and facial dimensions of specific face elements. Analysis of approaches that allow estimation of the height from the image is presented. Following the analysis, the experimental software solution is developed and consisted of two applications. The first enables the estimation of the height of a person standing in front of a video camera. Final prototype of the solution utilizes the technique of background subtraction from the foreground with the aim to separate of the object of interest. The ArUco marker is used as a reference object to allow exact height estimates. The second application follows the detection of a face and extracts the distance ratio among specific features of a face.
