Metrology, the science of measurement, is very important in the development of science and engineering principles if any meaningful progress will be made in these fields. This concept also applies to computer security if decision makers are to rely on judgment based on metrics. Management needs to establish how secured their organizations are, the amount of(More)
Homomorphic and non-homomorphic filtering have been used in speckle noise removal from images but the homomorphic technique is more widely used. In this paper, the performance the homomorphic and nonhomomorphic averaging filter, wiener filter and median filter were investigated. From the result of the simulations, the homomorphic median filtering gave(More)
Biometrics existed in antiquity but has in recent times re-emerged as a new field of study in Computer Science and Engineering. A biometric is a physiological (biological) or behavioral trait in a human, called an identifier that uniquely classifies each human. Fingerprint is one of the biological identifiers. Fingerprint recognition is largely used in(More)
This paper presents a technique for fingerprint image enhancement using wavelet processing. The algorithm developed uses Daubechies’ wavelets for decomposition as well as reconstruction of the fingerprint image. Experimental results indicate that this algorithm is quite effective, and performs quite competitively with existing methods. Index Terms —(More)
