How does image matching work? Jul 19, 2016 15:01:20 GMT

Hello,

Trying to create my own script for Pocket Maplestory and have run into a problem, the image recognition finds these two images to be "similar" enough to act as one.

pasteboard.co/1l11AJtuM.png
pasteboard.co/dobq3Hpt6.png

Is there anyway of using different image recognition settings to distinguish these? I understand that grayscale images may look similar because of the identical pattern.

Thanks in advance!

So I will be unable to use the image recognition methods and have to roll back to color detection instead? That is too bad, was really hoping to be able to just change the mode of image recognition.

Oh well, thanks for your fast response!

Not really actually!
AnkuLua turns the screenshots it makes into greyscale before finding the pattern, so it doesn't see any difference between a color and a greyscale image.
But you can still search for the image, and once the image is found check if it is greyscale or not!

Take a look at getColor in Advanced Methods to see how to test for greyscale.
