Sistema de medición del tamaño de la pupila con visión artificial para investigación en psicología e inteligencia artificial del Grupo IDEIAGEOCA.

Abstract

The objective of this work is to develop a system for measuring pupil size with artificial vision, for research in psychology of the IDEIAGEOCA Group. The system consists of two stages: image preprocessing and segmentation; in the first stage it uses image acquisition, image resizing and in the second stage it uses iris detection, pupil detection and pupil diameter measurement. The eye images used for experimentation were taken from two sources, from a camera and from the Internet. As a result of unifying the modules of the computer vision system (svc), 80 % reliability was obtained when measuring pupil size. Two metrics were used to evaluate the system, the accuracy and the error between the actual measurement and the automatic pupil measurement, therefore, the system is optimized while maintaining an acceptable level of efficiency.
