Abstract
This 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.
