Most fungal infections of the cornea are secondary infections, caused by opportunis tic fungi that have invaded a diseased cornea or one that has been treated with corticosteroids or broad-spectrum antibiotics. Two ex ceptions are corneal infections due to Can dida albicans or Aspergillus species; these may infect an apparently normal cornea af ter minimal trauma. Superficial mycotic infect...
The growing concern with security and access control to places and sensitive information has contributed for the increased utilization of biometric systems. Biometry is the name given to the techniques used to recognize people automatically through physical and behavioural characteristics of the human body such as those found on the face, fingerprint, hand geometry, iris, signature or voice. Fr...
A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is regarded as the most reliable and accurate biometric identification system available. Most commercial iris recognition systems use patented algorithms developed by Daugman, and these algorithms are able to produce perfect recognition ...
