Image analysis algorithms find the iris in a live video image (10) of a person's face, and encode its texture into an "iris code" (24). Iris texture is extracted from the image at multiple scales of analysis by a self-similar set of quadrature bandpass filters defined in a dimensionless polar coordi ...
