Abstract
The method of recognizing fingerprints comprises an analysis step () in which an expert analyses characteristic points of a fingerprint image so as to be able to differentiate the fingerprint whose image is presented to him. The method comprises a modification step () in which the said print image available with various levels from a grey scale is modified into a second image in which at least one grey range of the first image is parameterized so as to be represented with various levels from a colour scale. The modification makes it possible to identify the characteristic points on an unknown fingerprint image more accurately and also to compare the said image to other known fingerprint images more easily.
