Thermal Face Recognition: A Fusion Approach

One of underused biometric methods is the face recognition based on thermal images. Nevertheless, in the applications such as liveness detection or fever scan, the thermal face recognition is used as a standalone module, or as a part of a multimodal biometric system. This article presents an overview and comparison of various statistical methods for thermal facial image analysis and recognition. It also proposes an approach to fusion of some methods to improve the overall performance.
