how to do iris normalization?

I have read in most of he paper that it can b done through Dougman Rubber sheet algorithm .. but how to implement this ? is there any other function that can be use for iris normalization

Answer 1

To my knowledge there is no MATLAB code available that implements Daugman's Rubber-Sheet algorithm for iris normalization. However, you can find code to do the first step before normalization:

Daugman's iris segmentation algorithm

The full algorithm is described in the following paper:

John G. Daugman. High confidence visual recognition of persons by a test of statistical independence. IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol. 25, No. 11, pages 1148–1161, November 1993.

If you are still in need of such algoritm i posted one on the matlab exchange: http://www.mathworks.com/matlabcentral/fileexchange/51246-daugman-rubbersheet-normalization
