[Libface-general] Some questions

[Richard U. <ri...@pa...>]

Hi there,

I want to use libface in a new project 
http://sourceforge.net/projects/receptiongreet/

I understand that libface is not quite finished. 
Thus I would be happy to participate a bit in the development.
So, I have a few questions:
- Face Recognition doesn't seem to be implemented in the main interface
class (libface::LibFace).
- If I use the Eigenfaces class directly I run into some problems:
  - Training a person with only one face (image) fails. This seems to be
by design, but why is it necessary? -> Eigenfaces::doPCA() -> nEigens =
nTrainFaces - 1;
  - Finding a face in an already cropped image gives me a face with no
coordinates, which leads to problems later on in FaceDetect::finalFaces
in cvCopy near the end.
- FisherCore.cpp misses some includes, but it doesn't seem to be used
anyway.
- would you generally be opposed to using boost in some areas. I find it
to help a lot.
- LibFace.cpp line 110 -> filename.c_str() would be better than
filename.data().
- If I have fixes, shoudl I send diffs, or would you give me write
permission on the repository?
- If I get write permissions, what do I have to look for not to
interfere with the GSOC project?
- I saw that opencv has also a C++ interface. I don't know the status of
that. Is it incomplete? If it is usable enough, it might contribute to
readability and quality of the libface code.
