subspaceproject and reconstruct methods in python

edit

Hello,

I have searched through the web, but haven't found any answer so far to the following question, therefore I want to ask here if someone could help me out with that:

basically what i need is the same as in the solution from PraveenofPersia/Jesse there, but only the python implementation considering a Fisherface Recognizer: Any tips on confidence score for face verification (as opposed to face recognition)?

up to now I am facing the problem, that cv2 does not offer either subspaceProject nor any other.

thanks to a tip on another platform i have now tried to build opencv from sourc with a modified version of contrib.hpp (changed CV_EXPORTS Mat subspaceReconstruct(...) to CV_EXPORTS_W Mat subspaceReconstruct(...) respectively for subspaceProject). But i end up with a linker error saying:

Linking CXX shared library ..\..\lib\cv2.pyd
Creating library file: ..\..\lib\libcv2.dll.a
CMakeFiles\opencv_python.dir/objects.a(cv2.cpp.obj):cv2.cpp:(.text$initcv2+0x170
a): undefined reference to `__imp_Py_InitModule4'
collect2: ld returned 1 exit status
mingw32-make[2]: *** [lib/cv2.pyd] Error 1
mingw32-make[1]: *** [modules/python/CMakeFiles/opencv_python.dir/all] Error 2
mingw32-make: *** [all] Error 2

i am using python 2.7.5, numpy 1.8 both in 64bit versions, on a win7 64bit machine, cmake, mingw for compiling. i have created the python library (.a) file.

is there maybe anyone out there who could help me on this or maybe even provide me a recompiled cv2.pyd file with these methods (or even more) provided?
