Abstract
A method for selecting images from a set of images (according to sharpness and contrast criteria), comprising pre-selecting images by a simplified sharpness and/or contrast analysis of each image in the set of images, and of selecting images by a finer analysis of the sharpness and/or contrast of each pre-selected image. This method is particularly useful to perform an identification by recognition of the iris.
