Document Summary
1 st , 2 nd and 3 rd level detail. 2d level: minutiae & incipient rides (detail within the impression, what the rides are actually doing whether they"re spitting or coming to an end ) 3rd level: ridge edges and pores (physical shapes of the ridges themselves if looking at a magnifying view, you can see that they are not straight parallel lines there are features even within that ridge flow) You cannot make a consensus on first level detail alone most fingerprint identification are going to be done on 2nd level detail. Level 1 overall ridge flow: orientation, pattern type, focal points. Creases: identifications cannot occur at this level of information, however exclusions can occur. Spatial relationship: continuous ridges, identifications and exclusions can occur at this level of information. Level 3: size and shape of pores and ridges. Three types of level 2 characteristics: continuous ridges.
