Iris Recognition Using Discrete Cosine Transform and Relational Measures
Iris is one of the most currently used biometric trait as it has random discriminating texture which does not change over a person’s lifetime. It is unique for all individuals, even for twins and the left and right eyes of the same individual. This paper describes an iris recognition system which includes phases like segmentation, normalization, segregating unwanted parts like occlusion, specul...
متن کاملIris Recognition Using Discrete Cosine Transform and Wavelet Packet Decomposition
Iris recognition is basic technology for personal identification and verification and is most reliable and accurate for biometric identification system. Iris recognition system gives security to the organization and Institutes from the unauthorized access . Digital templates encoded from iris pattern using mathematical and statistical algorithms allow the identification of an individual. In thi...
متن کاملIris Recognition Using Discrete Cosine Transform and Artificial Neural Networks
Problem statement: The study presented an efficient Iris recognition system. Approach: The design used the discrete cosine transform for feature extraction and artificial neural networks for classification. The iris images used in this system were obtained from the CASIA database. Results: A robust system for iris recognition was developed. Conclusion: An iris recognition system that produces v...
متن کاملAn Effective method for Iris Recognition based on Discrete Cosine Transform
Iris is considered to be the most unique attribute possessed by an individual and is regarded as the most reliable form of biometric authentication. In this work we have implemented a simple but very effective method for iris recognition based on Discrete Cosine Transform. Here firstly the iris image is preprocessed and segmented. After preprocessing, the segmented image is then further process...
متن کاملImage Steganography Using Discrete Cosine Transform (DCT) and Blowfish Algorithm
Steganography is one of the methods of secret communication that hides the existence of message so that a viewer cannot detect the transmission of message and hence cannot try to decrypt it. It is the process of embedding secret data in the cover image without significant changes to the cover image. A cryptography algorithm is used to convert the secret messages to an unreadable form before emb...
