I've stumbled upon down the first step for developing face swap feature, and it's quite entertaining by itself. Facial tracking, poisson blending, and model creation. For this example it can be manually triggered, which means you can now finally safely faceswap with your cat!
You can try out the experiment yourself here , considering you have a webcam, are in a well lit area, and are using Chrome.
In trying to debug the facetracking problem from earlier, I am now capturing the image data for the mask on every frame. Because of the difference in scale, it creates almost a liquid effect which I thoroughly enjoy.
