It has been a long time since my last visit and I notice nill's request. This maybe too late but here is how you can search for an image inside another image. Opencv uses cvMatchTemplate and cvMinMaxLoc. #include <GDIplus.au3> #include <Memory.au3> #include <GUIConstantsEx.au3> #include <OpenCVFcns.au3> ;start dll opencv _GDIPlus_Startup() _OpenCV_Startup() ;// load IPL type image both images must have same number
