[Libface-general] Getting started issue

[Martitza M. <mar...@gm...>]

Hi.  I just started reading the OpenCV book, so my questions are simple.

My computer is running Ubuntu Lucid x64 and has OpenCV 2.1 (2.1.0-3ubuntu1
packages) installed.

I built libface-0.1 on Ubuntu Karmic, including -DBUILD_EXAMPLES,
-DBUILD_EXAMPLES_GUI and -DBUILD_DOCUMENTATION.  No errors.  Yeah!

So I launched the GUI and loaded an image.  When I clicked "Detect Faces" I
get an error (in my shell):

Cascade directory located as : /usr/share/opencv/haarcascades
opened
ERROR: Could not load classifier cascade.

I discovered that /usr/share/opencv was almost completely empty!  (Actually,
it has one file: OpenCVConfig.cmake.)  So I went looking for the Haar
filters and found them gzip'ed in
/usr/share/doc/opencv-doc/examples/haarcascades/haarcascades.  SO I copied
and unzipped all of them into /usr/share/opencv/haarcascades (where the
libfaceGUI expects to find them).

Now when I run libfaceGUI, it does recognize faces.  Yeah!  But each time it
recognizes a face, it prints several lines like this:

ERROR: Could not load classifier cascade.
ERROR: Could not load classifier cascade.
ERROR: Could not load classifier cascade.
ERROR: Could not load classifier cascade.
ERROR: Could not load classifier cascade.

These appear to come in blocks of 5, i.e. 5 or 10 or 15 at a time.  I've
just started looking in the source code.

If anyone has any friendly advice to help ease my learning curve, I will
appreciate your comments.

Thanks!
