Disini menggunakan dlib, yang katanya lebih baik daripada Haar-cascade based classifier OpenCV.

Ambil Muka / Face yang sudah di label
wget http://vis-www.cs.umass.edu/lfw/lfw.tgz tar -zxvf lfw.tgz
I'm going to select from this a list that only has an excess of 10 faces and save it into a file called big_db.
find lfw/ -mindepth 1 -maxdepth 2 -type d -exec bash -c "echo -ne '{} '; ls '{}' | wc -l" \; | awk '$NF>10{print $1}' > big_db
Next, I'm going to select 10 random people out of this list and copy them to another folder called training-images.
mkdir -p training-images cat big_db | shuf -n 10 | xargs cp -avt training-images/
If you'd like to recognize yourself, add a folder in training-images. Be sure to include many photos in which you're the single identifiable human face.
We're now doing to run face landmark detection on each photo which will
- Detect the biggest face
- Detect the facial landmarks (outer eyes, nose and lower lip)
- Warp affine to a canonical face
- Save output (96x96) to a file in an easy to access format
To do this, run
./util/align-dlib.py ./training-images/ align outerEyesAndNose ./aligned-images/ --size 96
Next, run feature extraction on each of the images.
./batch-represent/main.lua -outDir ./generated-embeddings/ -data ./aligned-images/
As a final step, train a classifier from generated representations.
./demos/classifier.py train ./generated-embeddings/
This will create a file called classifier.pkl in generated-embeddings folder.

5. Run To test if everything is working properly before working with the trained model from Section 4, let's try this on a pre-trained model. There is a pre-trained model on celebrities in folder. To test using this image, run
./demos/classifier.py infer models/openface/celeb-classifier.nn4.small2.v1.pkl images/examples/adams.jpg
Artifacts of sections 1~4 done on RPI are on this link. Be sure to extract it from /home/pi/ to produce /home/pi/fd_fr as the internal scripts are hardcoded to that location. I've made a couple of changes to the base as this is run on a 32bit environment. Running "git diff" from /home/pi/fd_fr/openface will reveal the changes.
This should correctly predict the sample image as Amy Adams which predicts with 81% certainty but on RPI is 34% which I find odd...
To complete the final leg of our journey, I recommend testing on yourself. I saved a photo of myself that I didn't include in the training set as sky_chon.jpg. To test the trained model on me, I run
./demos/classifier.py infer generated-embeddings/classifier.pkl sky_chon.jpg
To run using the webcam (dev/video0) on VGA.
./demos/classifier_webcam.py --width 640 --height 480 --captureDevice 0 generated-embeddings/classifier.pkl
Works like a charm!!
