Detect image under another window

[Nathan4]

Hello, I use the software "Super macro" to detect an image, but I wish it could do it even if the image is in a window under another one. If autohotkey can't do it either or if it's easier with another software, can you tell me which ? This is the image I need to detect https://images2.imgbox.com/ad/2c/o9jJkaOn_o.png
