Do you have any idea how expensive the ingredients are to make mind reading potions? You have made it a really bad habit of just posting code without explanation or hint of what the problem is as if you expect us to be able to read your mind.

'give me exception' is actually vague. I guess the library provided at least a hint of what went wrong.

Unhandled exception at 0x000007fefd7d9e5d in Opencv.exe: Microsoft C++ exception: cv::Exception at memory location 0x0031eb20

Ops. It looks the library itself had no idea on what was going on. Probably your best friend is the debugger, provided you have the library sources.

What does it look like? It's the correction to your code, as shown in the documentation.

syntax error

What exactly is the error, and what exactly is the definition of this function?
