Thermal hand image segmentation for biometric recognition. (arXiv:2202.11462v1 [cs.CV])

In this paper we present a method to identify people by means of thermal (TH)
and visible (VIS) hand images acquired simultaneously with a TESTO 882-3
camera. In addition, we also present a new database specially acquired for this
work. The real challenge when dealing with TH images is the cold finger areas,
which can be confused with the acquisition surface. This problem is solved by
taking advantage of the VIS information. We have performed different tests to
show how …
