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.
