The following demo introduces palm detection and sign recognition with deep learning. 

1. Palm detection is to find the palm in an image
Palm detection and hand skeleton model: mediapipe

2. Sign recognition is to identify the sign shown by your
Sign classification model: 3-layer Dense Neural Network
Classes: Unknown (not labeled on image) / Metal / Peace / Stop / OK
Source: Github

Steps:

1. The demo can be started by accepting the Adatkezelési Tájékoztató/Privacy Policy below.
