  • We can separate the face and apply an eye detector using face detection, which can be done with a high-resolution camera. We can use the resulting regions to perform iris segmentation and classification.
  • We can use a specific eye camera, which grabs an eye image to be classified. This can be done either with RGB or NIR.

Since the first approach is prone to a lot of problems, such as the resulting eye image having a low resolution, a more common approach is to use a separate eye camera that grabs the eye. This is the method that we will use in this chapter. An example of a captured ...
