OpenCV 3.0.0, FaceRecognizer and Python Bindings

edit

Awesome!! I don't know if I just plain missed it or if it's not immediately clear that the face module is not within the standard release, but that clears a lot of things up. I will clone and compile from the opencv_contrib repo and see if it works.

you're right, it's not immediately clear, what was moved where (or why).

Thank you so much for your help! Everything is set up now. One last question - how can I access the current API available? I am trying to use the train(), save() and predict() functions but can't seem to find a way to use it properly.

model.train(np.asarray(X), np.asarray(y))
AttributeError: 'cv2.face_BasicFaceRecognizer' object has no attribute 'train'

Typing in

$ python
>>> import cv2
>>> help(cv2.face_BasicFaceRecognizer)

doesn't help either.

apologies, i did not test it.

you're right, the created model is lacking all functions. something broken with the wrappers, i guess.

sorry for the bad news, but this is a plain bug, not an error on your side (or your fault even)

if you're bold, try to fix it manually: build/modules/python2/pyopencv_generated_types.h ~line 9043

static void pyopencv_face_BasicFaceRecognizer_specials(void)
{
    pyopencv_face_BasicFaceRecognizer_Type.tp_base = NULL;

change to:

static void pyopencv_face_BasicFaceRecognizer_specials(void)
{
    pyopencv_face_BasicFaceRecognizer_Type.tp_base = &pyopencv_face_FaceRecognizer_Type;

same for :

static void pyopencv_face_LBPHFaceRecognizer_specials(void)
{
    pyopencv_face_LBPHFaceRecognizer_Type.tp_base = &pyopencv_face_FaceRecognizer_Type;

rerun make install, but take care not to invoke cmake again (else it will overwrite your changes)

I think that seemed to fix it! I can successfully call

model.train(np.asarray(X), np.asarray(y))

I haven't tried save() or predict() since I have a couple of errors in my program (passing in an empty training set when calling train(), might be an error on my part), but thank you so much for your help! Hopefully anybody else who has the same problems as me sees this post and can follow your instructions.

One last note - is there a person or a page I can report this bug to so it can get fixed in the future?

try a help(model) to see, if the set of function is complete ( worked on my side)

i already tried to make an issue here , feel free to append, if you find anything missing there.

Yes, doing

>>> test = cv2.face.createEigenFaceRecognizer()
>>> help(test)

listed the face_BasicFaceRecognizer class with all the appropriate methods (save, predict, train, update, etc..) inherited from face_FaceRecognizer. Issue solved!

I am new to OpenCV and I tried all the previous steps and still stuck at the same point. AttributeError: 'module' object has no attribute 'face'

When I tried to explore this file: build/modules/python2/pyopencv_generated_types.h I found that pyopencv_face_BasicFaceRecognizer_Type.tp_base = &pyopencv_face_FaceRecognizer_Type; pyopencv_face_LBPHFaceRecognizer_Type.tp_base = &pyopencv_face_FaceRecognizer_Type;

What should I do ?
