**5.1 Accuracy of manual and automatic marking**

After manually marking the points via SW1, SW2 also searched for the same points automatically. With this principle, we determine the accuracy of the positions of points during manual marking. The resulting average deviation of a minutiae was about 5 pixels [5].

Simultaneously, the automatic algorithm tested on the VARIA database [27], contained 233 images from 139 individuals, is enhanced. The resultant image emphasizing the comparison is shown in **Figure 6**.

On the contrary, we assume that the hand marking will accurately highlight the blind and yellow spots. SW3 also compares the correct location of the automatic search. The success rates were 92.97% for the blind spot and 94.05% for the yellow spot. Wrong localization of spots was mainly caused by too much brightness or darkness in it.
