Sikuli is too slow or not robust. What can I do?

You can tune a parameter of the vision algorithm, MinTargetSize, to speed up the matching process or make it more robust.

1from org.sikuli.script.natives import Vision
2
3Vision.setParameter("MinTargetSize", 6) # A small value such as 6 makes the matching algorithm be faster.
4Vision.setParameter("MinTargetSize", 18) # A large value such as 18 makes the matching algorithm be more robust.
