AB  - Image enhancement is the one of the key factor to get better visual. The main purpose of image enhancement is to increase the brightness, noise removal. These conditions lead to image may suffer from loss of information. The main purpose of image enhancement is to bring out detail that is hidden in an image or to increase contrast form in a low contrast image. It provides multitude of choices for improving the visual quality of images. That’s why, it is used in huge number of applications with important challenges such as noise reduction, blurring etc. In this study some of image enhancement techniques for biometrics on spatial and frequency domain like thinning, thickening, skeleton and Gabor filters, etc. are applied and it is observed that Haar based wavelet transform gives better performance over other techniques.
