How to make selfies look like portrait photographs

There's nothing wrong with "big noses, weak chins, and sloping foreheads" but if you want to adjust your selfies to make them less distorted, give this a try. It's based on a research project called "Perspective-aware Manipulation of Portrait Photos" by Ohad Fried, Eli Shechtman, Dan B Goldman, and Adam Finkelstein. And was created by Brian McSwiggen and John Morone, advised by Ohad Fried and Adam Finkelstein.

paper introduces a method to modify the apparent relative pose and distance between camera and subject given a single portrait photo. Our approach fits a full perspective camera and a parametric 3D head model to the portrait, and then builds a 2D warp in the image plane to approximate the effect of a desired change in 3D. We show that this model is capable of correcting objectionable artifacts such as the large noses sometimes seen in "selfies," or to deliberately bring a distant camera closer to the subject. This framework can also be used to re-pose the subject, as well as to create stereo pairs from an input portrait. We show convincing results on both an existing dataset as well as a new dataset we captured to validate our method.
