Extending Controllable Color Gamut of a Projector by Inducing Visual Illusion
Using projection mapping, we can control the appearance of real-world objects by projecting colored light onto them. Because a projector can only add illumination to the scene, only a limited color gamut can be presented through projection mapping. Our aim is extending controllable color gamut of a projector by accounting for human perception and visual illusions. In particular, we induce color constancy to control what color space observers will perceive.
Robust Estimation of Reflectance for Appearance Control with a Projector-Camera System
There are many research with a projector-camera system that control projection interactively depending on the change of objects. Even when the objects change, the system can create projection images for appearance control if they can estimate original colors and textures successively. However, when we use a projector-camera system consists of several devices, we need to calibrate them. Color calibration is required to be done when light environments change, but it is not realistic to use this system as a light equipment. We proposed the methodology of robust estimation of reflectance in dynamic light environments to make the system maintenance-free.
You can see appearance control example from the left video. It controls appearance of photo, and cancelling the effect of red flash light.
