Iris Recognition

Hi,

I'm working with the DE2 board and the camera Terasic TRD-D5M (5 Mpixels).

I want to take a picture of the eye and extract all the features. I can take a picture, but the problem is that the iris is out of focus..is blurred. Is it possible adjust the focus of the sensor??

somebody has a trick that could help me?

I prove with different resolution cameras, zoom, and at different distances, but I can not see the features of the iris

Thanks in advance!!

    Did you make any progress with this? I too am having issues with bluriness.

    Deblur algorithms are complicated and require that you know ALL physical parameters of the lens and of the sensor.

    So first of all I advise you to find all information you can find about your camera.

    Doing so might have a very nice side effect: you might learn how to control the focus, and that will save you the trouble of implementing the deblur algorithm.
