Abstract [en]

We present two new applications for projector-camera systems; reflectance spoofing and video neutralization. With these applications we can project visual content in mixel reality environments without making the light levels unnatural and we can project color compensated movies and images on non-ideal projection surfaces.

A custom developed structured light technique is used to calibrate the correspondence between camera pixels and projector pixels. A feedback algorithm is used to establish a neutralization image on a per pixel basis. Our results show real promise for this kind of technology.

A new method for spectral calibration of digital cameras is also presented. The method uses laser pointers to mark wavelengths in a spectrum created with a tungsten light source and a diffraction grating. The method is faster and potentially much cheaper than current methods and our results suggest that the method gives results of better or equal quality compared to currently availible methods.
