Webcam Augmentation with Python and ArUco Markers
This repository demonstrates how easy we can bring emotions back to video chat programs when wearing face masks. Imagine you are in an important video meeting while you are at a public place or a train where face masks are mandatory. You could be misunderstood as you have limited opportunities to express your emotions. By attaching an ArUco marker to your face mask and using my python script, you can easily enhance your emotions. The tutorial explains how you can use OBS Studio to augment your webcam stream in any video chat software on your PC. I used this script to teach my students basics of augmented reality and markers. The emojis were taken from OpenMoji.
