stitching_detailed sample code unhandled exception when run

edit

I was trying out the sample code stitching_detailed.cpp. It built successfully but has the following error when run:

Unhandled exception at 0x00007FFDE7011F28 in stitching_detailed.exe: Microsoft C++ exception: cv::Exception at memory location 0x000000935AF3B820.

However, when I build and run the other sample code stitching.cpp it works fine. I'm using opencv 3.1 on visual studio 2015.

Edit 1: The link to the stitching_detailed.cpp code is here. When I try to run it, it points to return Ptr<T>(new T()); of the following part of code in here:

Ptr<T> makePtr()
{
    return Ptr<T>(new T());
}

Edit 2

When I ran the program in the command line it showed this error:

OpenCV Error: The function/feature is not implemented (OpenCV was built without 
SURF support) in cv: : detail: :SurfFeaturesFinder: :SurfFeaturesFinder, file C: \bui 
ldslave64\win64 amdoc1\master PackS1ave-win64-vc14-shared\opencv\modu1es\stitchi 
ng\src\matchers . cpp, line 361

It seems that for this opencv version the feature is not installed (it is in a separate opencv_contrib module). Will try it.

Edit 3 (Found solution)

The error occurred because I didn't install the separate opencv_contrib module which has a feature (SURF feature detection) that is used in the program. It ran with no errors after compiling opencv with the opencv_contrib module using cmake.

For more details, I followed instructions on compiling it through this website: https://putuyuwono.wordpress.com/2015...
