Face relighting with radiance environment maps
2003 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003. Proceedings.
Preserved Fulltext
In order to use this technique for human face relighting, we have developed a technique that uses spherical harmonics to approximate the radiance environment map for any given image of a face. ...
A radiance environment map pre-integrates a constant surface reflectance with the lighting environment. It has been used to generate photo-realistic rendering at interactive speed. ...
Thanks Brian Guenter for the face albedo map. ...

Light-transport Field (NeLF) produce a portrait from a new camera view under a new environmental lighting. ...
We can easily imagine how the face will look like in another setup, but computer algorithms still fail on this problem given limited observations. ...
The light-transport is a vector whose dotproduct with the global environment map produces the outgoing radiance at the 3D point. ...

We present a novel Relightable Neural Renderer (RNR) for simultaneous view synthesis and relighting using multi-view image inputs. ...
We assume that background pixels lie faraway, so we establish the image-to-panorama mapping and fill in the environment map with image pixels. ...
