Table 1 Probabilities for legitimate and random edge detection

From: Optimal edge detection using multiple operators for image understanding

 

Legitimate edge detection

random edge detection

TP

d1,1 = P · SE

c1,1 = P · Q

FP

d1,2 = P' · SP'

c1,2 = P' · Q

FN

d2,1 = P · SE'

c2,1 = P · Q'

TN

d2,2 = P' · SP

c2,2 = P' · Q'
