Biometric Eye Model and Ray Tracing for Improved Iris Recognition Iris recognition has proven to be an accurate and reliable biometric, especially as a means of verifying personal identity. However, iris recognition is limited by the quality of the images presented to the analysis system. Ideal images are typically direct, on- axis frontal views of the iris. Recognition of nonideal images, such a…
