Abstract

The appearance of an object or scene is determined by factors like the material, the lights, the geometry, the position of the observer, and the surroundings.
Changes in these factors can be simulated using a projector-camera setup.
Other research focuses on changing the appearance from the perspective of the projector, or on projector compensation for slightly warped planar surfaces.
This paper aims to simulate changes in the scene's appearance by actively manipulating the lighting using a projector-camera setup.
It works on not only planar surfaces, but also on more complex geometries.
This is achieved by first doing a calibration, and then using this to optimize a projection.
This projection is optimized to minimize the difference between how the scene looks when the projection is projected and the desired scene.
For low-resolution projectors, it can do this in a few seconds to half a minute.
For higher resolutions, the calibration time and file size get quite big.
This can be solved in future work using different calibration methods.
