First of all, i wanna say hi to all glad that I'm a member of autoit community and this is my first time to post for new topic, okay, now im gonna start the topic. I think a lot of you here knows "Opencv", if not, OpenCV (Open Source Computer Vision) is a library of programming functions for real time computer vision, Here's the OpenCv Documentation or you can download free the installation and samples Here Okay, so what im trying to do for now is to make OpenCv UDF supported with thisReferences and Documents by calling Opencv dlls(cxcore.dll,cv.dll,highgui.dll) using autoit dllcall function. BTW i tried searching it in the forum but no success, i guess if i'm not wrong, this is the first topic about opencv. If any one interested, feel free to help . i know its possible in autoit.
