Image enhancement plays an important role in fingerprint recognition System. In this paper, the authors study the different techniques of enhancement of a fingerprint image in which have been used in previous work. There are so many techniques for enhancement which uses so many different image processing approaches. During study some approaches are found in spatial domain, frequency domain, some are neural network based and some are fuzzy based. Most of the fingerprint techniques use contextual filters or multi-resolution filters whose parameters depend on the local ridge frequency and orientation. The main drawback of these methods lies in the fact that false estimate of local ridge direction will lead to poor enhancement.
