Figure 7.141 Appearance of Threshold Adjustment Panel With Min+Offset Mode
Figure 7.142 illustrates the Min+Offset threshold mode, using 69 for the
“ Offset ” setting and 255 for the “ Limit ” setting.
Figure 7.142 Example: “Min+Offset” Threshold Mode
Minimum gray
scale value = 115
High limit = 255
Threshold at offset plus
minimum gray scale value
level (115 + 69 = 184)
In this example, the profile tool finds the minimum gray scale value at 115. It
then adds offset value 69 to minimum value 115 and places the threshold at
the 184 gray scale level (69 + 115 = 184).
