摘要 A method and a system for evaluating the definition of the image of an eye iris or the like, consisting of approximately localizing the pupil in the image, defining, from the approximate position of the pupil, an examination window centered on this position, and applying a gradient accumulation operation to the luminance values of the pixels of the examination window, the running total being proportional to the definition score of the image.
