The directory tree built to hold the face labeled files is similar to the master photo directory tree except that “-labeled” has been added to all the file names of the labeled versions of the photos. This was done because it was too confusing to have files with the same names for both the input photos to be tagged and the output photos with the person label written over the photo. Thus, if there is a photo such as myAunt.png, the output photo will be myAunt-labeled.jmp.
Additionally, all output labeled photos are jpegs instead of png to save disk space.
Finally, directories are skipped if there are no people identified in the photos. This often occurs on directories containing text documents, for instance.
