Abstract: One of important factor affecting the overall performance of biometric system is quality of biometric data. Poor quality of biometric sample mostly results in spurious or missing features, which increases the enrollment failure and degrade the overall performance of biometric systems. Finding the quality of an image is the fundamental problem in image and video processing. For quality assessment of an image various methods have been estimated. Quality of biometric sample can be defined in two ways: one is subjective and other is objective methods. In this paper survey on the image quality assessment techniques which are necessary to improve the performance of biometric system is presented.
