A Review On Digital Image Processing In Biometrics

Digital image processing is the technology of manipulating pixels of the digital pictures to enhance the quality of the picture that is digital in nature or create a different perspective or to fetch information from the image digitally, with the utility of simple or complex computer algorithms. In this review, the digital image processing in the field of biometrics has been discussed. Several biometric applications and different types of biometric along with the role of image processing in biometrics are explained here. Digital image procession has allowed wide criteria of algorithms. That is used to the input biometric sample. The comparison of biometric images is made using image comparison techniques. The existing researches in biometric and their objectives are stated. This paper also discussed the scope of digital picture processing.
