Face Recognition
[NOT ACTIVELY MAINTAINED] A light weight face recognition implementation using a pre-trained facenet model. Most of the code is taken from David Sandberg's facenet repository.
Steps to follow:
-
Make the following changes : In lib/src/create_face_embeddings.py replace the data and pb file paths by your owns (you can also optionally turn on your GPU : with tf.Session(config=tf.ConfigProto(device_count={'GPU': 0})) as sess: ) In server/rest-server.py modify the paths
-
Create a dataset of faces for each person and arrange them in below order
root folder
│
└───Person 1
│ │───IMG1
│ │───IMG2
│ │ ....
└───Person 2
| │───IMG1
| │───IMG2
| | ....
- Align the faces using MTCNN or dllib. Please use the scripts available in lib/src/align. For this project i aligned faces using MTCNN.(Please have a look at aligning faces if you need any clarifications)
[Before alignment]
[After alignment] 
- Download pre-trained-weight ,extract and keep it in lib/src/ckpt folder (for detailed info about availabe weights: available-weights)
- Create face embeddings using pre-trained facenet model. Run the below scripts by changing the folder paths.(edit paths in lines)
python lib/src/create_face_embeddings.py
Once you run the script succesfully, a pickle file with name face_embeddings.pickle will be generated inside lib/src folder
- Start the server by running the command
python server/rest-server.py
access the UI using url https://127.0.0.1:5000. It will show a button with face recognition as label. Once you click on it, automatically your primary camera will get turned on and start recognizing the faces.
sample result

NOTE: The faces are identified using retrievel method, instead if you have enough data, you can train a classifier on top of face embeddings (Train-a-classifier-on-own-images)
