Abstract
In a method and an arrangement for assessing the quality of skin print images, and particularly fingerprint images, provision is made for gradients to be formed for the individual picture elements (pixels) of the skin print image, for a mean value to be formed from the gradients of the pixels in one region of the image (tile) at a time, and for similarities in the mean values from tile to tile to form a measure of quality.
