Review on latent fingerprint matching techniques

The best form of identifying a person for criminal investigation is from the fingerprint. Identifying suspects based on latent fingerprint is a procedure that is extremely important to forensics and law enforcement agencies. The small number of minutiae and the noise characteristic of latents make it extremely difficult to automatically match latents to their mated full prints that are stored in law enforcement databases. The various latent enhancement techniques and matching algorithms are discussed in this paper.
