Methods of face localization in thermograms

This paper presents an algorithm for determination of the head centre in thermograms. The paper includes a comparison of the method developed by the authors with the known methods presented in the literature for locating the head in thermal images. The proposed method enables automatic localization of the head centre, which is essential for practical applications when there is a need to locate the head in an image. Application areas may include the process of face recognition in biometrics, recognition of emotions, the creation of a human–computer interface. The presented method is reproducible and enables to obtain correct results in cases of large interindividual variability of the test subjects.
