Subtraction:
This is a function to extract a pixel that exceeds a certain degree of the difference in the gray value when
the detected image is overlapped with the template. The feature allows you to detect up to 128 of
subtraction parts that are difficult to reflect the correspondence value, and judge according to the number
of subtraction parts exceeding a certain size.
Item
Description
Subtraction
Threshold
Extracts a pixel that exceeds a certain degree of the difference in the gray value
between them when the detected image overlaps the template. The lower the
Subtraction Threshold value, the stricter extraction standard.
Filter
Dilates or erodes the extracted pixel clusters, or does so after dilation or erosion. Use
the Filter function to enhance the extracted pixel cluster or remove a fine noise or dust.
Subtraction Area
Min.
Detects only the pixel clusters having the area value more than the Subtraction Area
Min. For example, if you want to exclude the 10 pixel or less extracted subtraction parts
from the standard for judgement, set to 11.
