Face recognition using thermal infrared images for Human-Robot Interaction applications: A comparative study

The aim of this work is to carry out a comparative study of face-recognition methods for human-robot interaction (HRI) applications using long wave infrared images. The analyzed methods are selected by considering their suitability for HRI use, and their performance in former comparative studies. The methods are compared using visible and infrared (8-12 ¿m) images. The results of this comparative study are intended to be a guide for developers of face recognition systems for HRI.
