This repository provides a deep convolutional neural network model trained to detect moments of eye contact in egocentric view. The model was trained on over 4 millions of facial images of > 100 young individuals during natural social interactions, and achives an accuracy comaprable to that of trained clinical human annotators.
- PyTorch 0.4.0
- opencv 4.0.0
- numpy 1.16.2
- PIL 5.3.0
- pandas 0.23.4
- dlib 19.13.0 (optional if you want live face detection)
python demo.py
python demo.py --video yourvideofile.avi
Try this if you don't want to use dlib's face and instead test with pre-detected faces.
Comment out the first line of demo.py "import dlib" if you didn't install dlib.
python demo.py --video demo_video.avi --face demo_face_detections.txt
Demo video has been downloaded from here. I used this face detector to generate the face detection file.
--face: Path to pre-processed face detection file of format [frame#, min_x, min_y, max_x, max_y]. If not specified, dlib's face detector will be used.-save_vis: Saves the output as an avi video file.-save_text: Saves the output as a text file (Format: [frame#, eye_contact_score]).-display_off: Turn off display window.- Hit 'q' to quit the program.
- Output eye contact score ranges [0, 1] and score above 0.9 is considered confident.
- To further improve the result, smoothing the output is encouraged as it can help removing outliers caused by eye blinks, motion blur etc.
