Doge meme style generator with ML5 PoseNet

Example of

Week 5: Doge style generator using ML5 PoseNet. This is not the best practice to use PoseNet, because a similar effect can be done through random(width), random(height) - not necessarily involving the person's pose. Yet it still makes a difference in a sense that it won't generate any text if it doesn't detect a person inside video. What can possibly done to use pose vertex with text in more apparent way..?
