according to conventional methods, fingertips with the arch pattern were being assigned a ridge depend of zero. Fingertips which has a loop sample Use a ridge rely equal to the number of ridges crossing the single straight line. For fingertip designs with two triradial details e.g., whorls, the next ridge counting protocol was employed As outlined by Kahn et al., [12]: ridge depend = ridges crossing the for a longer time line + half of ridges crossing the shorter line.
