OpenCV Exception

[COLINDBB]

Hello!

I'm seeing an exception thrown in matchTemplate
what(): OpenCV(4.1.1-dev) /opencv/modules/imgproc/src/templmatch.cpp:1109: error: (-215:Assertion failed) _img.size().height <= _templ.size().height && _img.size().width <= _templ.size().width in function 'matchTemplate'

Do you know what the issue may be here?
These are my input images.

template image should be smaller than source no matter in width or height

@DennisLiu1993: can you tell me how can I run this project in python code as your demo because I am not familiar with C++??

extract pure c++ part to a class, and built it with an interface then it can be imported by python using ctype or pybind11

Yeah, thanks so much for your reply. I spent hours to read file .cpp and .h in matchtool folder. Can you show me which library .cpp and .h is necessary? Basically, I just need the code that I input an image and take the result. So I tried to find the relationship between your libraries, but it is really difficult since there are so much code !!

just focus on matchToolDlg.cpp/.h
