Question #218387 on Sikuli changed:
https://answers.launchpad.net/sikuli/+question/218387

    Status: Open => Answered

RaiMan proposed the following answer:
the larger the image, the more the find depends on that most pixels on the screen and in the probe are identical.
If there are too many differences (which might not be obvious for the user looking at the screen), the the similarity score drops beyond  0.7 (the minimum similarity score) and the find fails.

you might use the IDE's preview window (klick on thumbnail, while the
screen is showing the image) and check.

you might reduce the search objects to smaller areas, that might be
found with a higher score.

Usually it is more robust to look for 2 or 3 smaller images, than for a
large one.
