Going into this paper, i expected they would be correcting for barrel distortion. I was disappointed to read that they instead: >we formulate an optimization problem to create a content-aware warping mesh which locally adapts to the stereographic projection on facial regions, and seamlessly evolves to the perspective projection over the background. Reminds me of this person who wrote a youtube tutorial with the factually incorrect title "Manually correct perspective in Photoshop". He did not correct the (already correct) perspective, but rather selectively distorted parts of scenery photographs so bridges looked "vertical". In fact, he was making those parts of the image no longer conform to the mathematical photo projection. Instead of picking a better-suited image projection, that video and this paper selectively fudge parts of the image to use a different projection. https://youtu.be/BocAGkS8yRQ https://youtu.be/BocAGkS8yRQ
