Cropping the Undergraduate Faces

EigenFaces:

Average Face:

Program output | .bat | .face | .user 

Undergraduate Faces and Cropped Faces:

min_scale = 0.18, max_scale = 0.25, scale step = 0.01

result: 12 correct, 3 incorrect croppings

If the min_scale is too small then the image will be scaled down to be smaller then the eigenfaces.  Then it will be impossible to search the image and the program will crash.
