Study of identification of criminals and dupe by androgenic hair patterns

Identifying criminals and victims is always an important task in police investigation and forensic evaluation. Finger marks, blood samples, DNA, dental records, tattoos, face images and face sketches are used regularly by law enforcement agents all around the world. However, they cannot handle the cases, where only images describing crime scene specimens are available Nowadays Identifying criminals and victims in images (e.g., child pornography and masked gunmen) can be a challenging task, especially when neither their faces nor any mark are observable. Skin mark patterns and blood vessel patterns are recently proposed to address this problem. However, they are invisible in low- resolution images and dense androgenic hair can cover them completely. Medical research results have implied that androgenic hair patterns are a stable biometric trait and have potential to overcome the weaknesses of skin mark patterns and blood vessel patterns. We are using Artificial Neural Network for the matching of the images. It is a fast growing field. To the best of our knowledge, no one has studied androgenic hair patterns for criminal and victim identification before. This paper aims to study matching performance of androgenic hair patterns in low resolution images.
