If you compile dlib
manually with CUDA support (after having installed CUDA and cuDNN), it will use the GPU for generating the face embeddings. So that's a bit faster. However the part that still isn't GPU-accelerated is finding the locations of the faces in each image.
Also the face_recognition script isn't caching anything, so it's rescanning all the known_images each time you run the program which is slower than it needs to be.
One way to speed things up a little bit would be to change the script to pre-cache the face embeddings for each known image and save them somewhere:
- Cache the results of running
face_recognition.face_encodings(unknown_image)[0]
on each known image. You only need to do that once. - When you want to test an unknown picture, load those cached results into an array called
cached_known_faces
or something and pass that toface_recognition.compare_faces([cached_known_faces], unknown_face_encoding)
.
I want to work on improving performance in general, but I haven't had a chance yet.

Thanks @ageitgey for the clarification.
