Face Recognition

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:

1. 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

2. Create a dataset of faces for each person and arrange them in below order

root folder  
│
└───Person 1
│   │───IMG1
│   │───IMG2
│   │   ....
└───Person 2
|   │───IMG1
|   │───IMG2
|   |   ....

3. 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]

4. Download pre-trained-weight ,extract and keep it in lib/src/ckpt folder (for detailed info about availabe weights: available-weights)
5. 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

6. 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.

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)
