Crop Your Face

A weird game that lets you make your face fly away when you do a "pistol gesture".

1. What's it like?

Like this?

2. Package Requirements

• tensorflow==2.1.0 (I don't know if TF1 could work. Probably will?)
• dlib==19.18.0
• numpy
• cv2
• csv

Use requirements.txt to auto install by typing this at your terminal:

$ pip install -r requirements.txt

3. Model Requirements

Most of the models are included in the model/ folder. However, you still need to download a large one from dlib.
If your computer supports curl command, try running setup.sh although I don't know if it works :)

$ bash ./setup.sh

If it doesn't work, you can manually download the model from here and put it inside model/
(Don't rename it!)

4. Get started

Run the main file:

$ python main.py

And wait for your webcam to launch.

5. Details

Face detection

Two models are used, both from dlib.
get_frontal_face_detector() is a detector that gives us the bounding box of faces.
shape_predictor, applied on dlib's pretrained 68 landmarks model, gives us the landmarks of detected faces.
Landmarks are indexed in the following order.

Palm detection

Two models are used, both from mediapipe.
palm_detection.tflite gives us the bounding box of detected palm.
hand_landmark.tflite gives us the landmarks of detected faces.
Landmarks are indexed in the following order.

6. Others

In fact, palm_detection.tflite from mediapipe cannot be loaded alone because there's some custom operators defined in their repo, and I don't want to dig into it too much.

However, thanks to metalwhale's awesome repo, which provided us a modified version of the model: palm_detection_without_custom_op.tflite so that combined with his code from hand_tracker.py, I was able to get the model to work.
