What does "Synthetic Iris Images" mean?
Table of Contents
Synthetic iris images are artificially created pictures of the colored part of the eye, known as the iris. These images are used primarily in biometric systems, which help identify individuals based on their unique iris patterns.
Importance
Using real iris images can raise privacy issues and there may not be enough data available for research and development. Synthetic iris images help solve these problems by providing a larger set of images that researchers can use to train and test recognition systems.
How They Are Made
Recent advances in technology allow us to create synthetic iris images using a method called Generative Adversarial Networks (GANs). This method involves two parts: one part creates images based on existing iris patterns, while the other part checks if the images look realistic. Some methods even separate the unique identity of the iris from its style, allowing for more variety in the images generated.
Benefits
Synthetic iris images can enhance the performance of iris recognition systems, making them more accurate. They can also help in improving the systems that detect unauthorized attempts to mimic real irises, known as presentation attacks. Overall, these synthetic images provide valuable resources for advancing iris recognition technology.
