Abstract:
A real-time algorithm for driving multispectral LED lights in a spherical lighting reproduction stage to achieve accurate color rendition for a dynamic scene. This technique drives several thousand multispectral LED lights at video framerate by pre-computing a LUT of the NNLS solutions across the full range of input RGB values.
