• Abstract: Photographs of people taken by professional photographers typically present the person in beautiful lighting, with an interesting pose, and flattering quality. This is unlike common photos people can take of themselves. In this paper, we explore how to create a ``professional'' version of a person's photograph, i.e., in a chosen pose, in a simple environment, with good lighting, and standard black top/bottom clothing. A key challenge is to preserve the person's unique identity, face and body features while transforming the photo. If there would exist a large paired dataset of the same person photographed both ``in the wild'' and by a professional photographer, the problem would potentially be easier to solve. However, such data does not exist, especially for a large variety of identities. To that end, we propose two key insights: 1) Our method transforms the input photo and person's face to a canonical UV space, which is further coupled with reposing methodology to model occlusions and novel view synthesis. Operating in UV space allows us to leverage existing unpaired datasets. 2) We personalize the output photo via multi image finetuning. Our approach yields high-quality, reposed portraits and achieves strong qualitative and quantitative performance on real-world imagery.

  A light stage uses a series of calibrated cameras and lights to capture a subject's facial appearance under varying illumination and viewpoint. Unfortunately, light stages are often inaccessible: they are expensive and require significant technical expertise for construction and operation. We present SunStage: a lightweight alternative to a light stage that captures comparable data using only a smartphone camera and the sun.

  We present an approach for high-quality intuitive editing of the camera viewpoint and scene illumination in a portrait image. Most editing approaches rely on supervised learning using training data captured with setups such as light and camera stages. We design a supervised problem which learns in the latent space of StyleGAN. This combines the best of supervised learning and generative adversarial modeling.

We propose a novel nearest pose search module that makes the reposing task easier and enables the generation of multiple neutral-pose results.
