Dlib: Question : face_chip from frontal_face_detector

[MyraBaba]

Hi,

Is there any decent way to extract face_chip at frontal_face_detector ? I tried and get below error:

‘dlib::rectangle dlib::full_object_detection::rect’ is private within this context
                     extract_image_chip(img, get_face_chip_details(shapes[i].rect, 150, 0.25), face_chip);

I know probably this is not an issue but its lock me down.

Yes, you can. Read the documentation for extract_image_chip().

I read and couldn't find the correct way :( .
I tried:
extract_image_chip(img, get_face_chip_details(shapes[i], 150, 0.25), face_chip);
and it returns empty chip. So I have error in the face_id extraction. Is it different than the DNN version of the extraction ? It is working in DNN but not in the frontal version. Clearly I am missing something.

What documentation did you read?

[MyraBaba]

http://dlib.net/dlib/image_transforms/interpolation_abstract.h.html#extract_image_chips

I am also following the example at dnn_face_recogniton_ex.cpp (there is a working face chip extraction). Sorry for taking your time Davis.

I'm just trying to teach you how to read documentation :)

So you see that the function takes a chip_details? Did you read the
documentation for chip_details to see how to make one? I think if you read
it you would see how to do this.

:) working on it :)

Finally i figure it out.

nothing !!!

I re-write from the beginning and the same code. I looks like it was the curse of the IDE cLiON ..... I should call it cCat (seaCat) . it is drowning sometimes :((

Davis are you using any IDE ? what would you suggest ?

[davisking]

I use Vim for all my C++ work.
