I'm applying for an KDE svn account soon. SVN should be unblocked in my
campus soon, too.
Thanks for the document.
True, if the face size is 100*100 pixels, then resizing and detecting could
be a problem. Currently libface correctly detects faces of size 50*50
pixels, faces smaller than that don't get detected nicely. So that IS a
problem. But once we detect the tiny faces, we can resize the region box for
the image of the original scale, and then clip the face from the original
image for training. So here, it won't damage training by feeding bad quality
faces, it will only damage detection.
