Image matching algorithm basic o advanced

[momolopu]

In the option mouse and keyboard > move the mouse over an image, in the advanced section there is an option called "image matching algorithm" that by default is set to "basic" if I change it to "advanced" it changes a lot and recognizes much better the images or really there is not much difference?

Thank you very much for your time.

For 2+ years, I have always used Basic and never had an issue, but here's this:

"In the advanced settings of these actions, you can select which image matching algorithm you want to use. The Basic algorithm achieves better results with images less than 200x200 pixels, while the Advanced algorithm is more effective with bigger images and more robust to color changes.

The Tolerance field defines the acceptable ammount of differences between the provided image and the image is compared with. High tolerance values may affect the precision of image recognition."

Hope this helps!

In my personal experience, Advanced with a 15 Tolerance has given me the best result, in any scenario.

It is that as it comes as standard it usually fails quite a lot and of course then it spoils the whole automatic process because it is stopped.

Yeah. I also have better luck when I add about a 5 second wait before the image action.
