<p>During expert examination of fingerprints characteristic and distinguishing points are identified and in an additional stage the luminance (l) perceived by the eye to varying shades of grey (G) is modified by amplifying red, green or blue in a particular range of grey defined by thresholds and suppressing them outside the range. This enables transitions at characteristic points to be shown more clearly as color changes An Independent claim is also included for: An information system which uses the method of representing ranges of shades of grey by colors to improve fingerprint analysis</p> |
