“…In recent years, long-wavelength infrared (LWIR) images, a.k.a. thermal images, have shown to be useful to efficiently solve problems from different domains (e.g., security monitor [ 10 ], medical imaging [ 11 ], car assistance [ 12 ], visual inspection [ 13 ], and human detection [ 14 ], among others) because thermal images have the information of the radiation emitted by the surface of an object (temperature above zero [ 15 ]) captured by thermal cameras. As mentioned above, thermal cameras play an important role in different areas.…”
