Hi,

What are the ages of the children? A good portion of the training data are
children starting from the age of 4. When you say you've used FLIRT, have
you used the first_flirt script? If not, were you registering with or
without skull? If so, what is it the first stage that went wrong? Is there
a lot of neck in the image?

Cheers,

Brian
