Software Module
Function Field
A window can be opened in the function field which serves as an adjustment tool for
the threshold module.
Opening the adjustment tool
The gray area identifies the area for black pixels.
The red area identifies the area for white pixels.
11.7.2.1.Magic Wand
The tool “Magic Wand” is an adjustment aid for “Module Threshold” and “Module Threshold HSV”. With this
tool the first settings for the threshold values can be achieved. It is possible that there will be a need to tune the
threshold values afterwards.
Opening the tool
The Procedure:
While activating the tool “Magic Wand” the View changes to the linked input image. Clicking to the position in
the image that is defined as foreground in the application will determine the coordinates and forward them to
the algorithm. The algorithm calculates the new binarization thresholds (Threshold Low and Threshold High),
and these results can be seen after.
Calculation of the threshold values:
Threshold Low = Brightness value at position of click - 20
Threshold High = Brightness value at position of click + 20
Both threshold values are limited to a range of [0...255].
Attention: The Module Threshold HSV calculates the threshold values for all three channels.
