Does Inverse Lighting Work Well under Unknown Response Function?
2015
Proceedings of the 10th International Conference on Computer Vision Theory and Applications
Inverse lighting is a technique for recovering the lighting environment of a scene from a single image of an object. Conventionally, inverse lighting assumes that a pixel value is proportional to radiance value, i.e. the response function of a camera is linear. Unfortunately, however, consumer cameras usually have unknown and nonlinear response functions, and therefore conventional inverse lighting does not work well for images taken by those cameras. In this study, we propose a method for
