A Linux script would look something like:
./main --eigenfaces 10 25 25 nonsmiling_cropped/list.txt eig10.face
./main --constructuserbase eig10.face nonsmiling_cropped/list.txt base.user
for i in smiling_cropped/*.tga; do ./main --recognizeface $i base.user eig10.face 1; done

This would do the recognition test for 10 eigenfaces; look over the
results and count up the successes.  Of course, if you're really
clever you can modify the program to generate all the data without any
interactive work on your part...


A DOS script

main --eigenfaces 10 25 25 nonsmiling_cropped/list.txt eig10.face
main --constructuserbase eig10.face nonsmiling_cropped/list.txt base.user
for %%A in (smiling_cropped/*.tga) do (main --recognizeface smiling_cropped/%%A base.user eig10.face 1)
