## News
|
|
|
|
+ 2016-01-19: OpenFace 0.2.0 released!
|
|
See [this blog post](http://bamos.github.io/2016/01/19/openface-0.2.0/)
|
|
for more details.
|
|
|
|

|
|
|
|
OpenFace is a Python and [Torch](http://torch.ch) implementation of
|
|
face recognition with deep neural networks and is based on
|
|
the CVPR 2015 paper
|
|
[FaceNet: A Unified Embedding for Face Recognition and Clustering](http://www.cv-foundation.org/openaccess/content_cvpr_2015/app/1A_089.pdf)
|
|
by Florian Schroff, Dmitry Kalenichenko, and James Philbin at Google.
|
|
Torch allows the network to be executed on a CPU or with CUDA.

### Isn't face recognition a solved problem?
|
|
No! Accuracies from research papers have just begun to surpass
|
|
human accuracies on some benchmarks.
|
|
The accuracies of open source face recognition systems lag
|
|
behind the state-of-the-art.
|
|
See [our accuracy comparisons](http://cmusatyalab.github.io/openface/models-and-accuracies/)
|
|
on the famous LFW benchmark.

# Overview
|
|
|
|
The following overview shows the workflow for a single input
|
|
image of Sylvestor Stallone from the publicly available
|
|
[LFW dataset](http://vis-www.cs.umass.edu/lfw/person/Sylvester_Stallone.html).
|
|
|
|
1. Detect faces with a pre-trained models from
|
|
[dlib](http://blog.dlib.net/2014/02/dlib-186-released-make-your-own-object.html)
|
|
or
|
|
[OpenCV](http://docs.opencv.org/master/d7/d8b/tutorial_py_face_detection.html).
|
|
2. Transform the face for the neural network.
|
|
This repository uses dlib's
|
|
[real-time pose estimation](http://blog.dlib.net/2014/08/real-time-face-pose-estimation.html)
|
|
with OpenCV's
|
|
[affine transformation](http://docs.opencv.org/doc/tutorials/imgproc/imgtrans/warp_affine/warp_affine.html)
|
|
to try to make the eyes and bottom lip appear in
|
|
the same location on each image.
|
|
3. Use a deep neural network to represent (or embed) the face on
|
|
a 128-dimensional unit hypersphere.
|
|
The embedding is a generic representation for anybody's face.
|
|
Unlike other face representations, this embedding has the nice property
|
|
that a larger distance between two face embeddings means
|
|
that the faces are likely not of the same person.
|
|
This property makes clustering, similarity detection,
|
|
and classification tasks easier than other face recognition
|
|
techniques where the Euclidean distance between
|
|
features is not meaningful.
|
|
4. Apply your favorite clustering or classification techniques
|
|
to the features to complete your recognition task.
|
|
See below for our examples for classification and
|
|
similarity detection, including an online web demo.
