  text: The unintentional scattering of light between neighboring surfaces in complex
    projection environments increases the brightness and decreases the contrast, disrupting
    the appearance of the desired imagery. To achieve satisfactory projection results,
    the inverse problem of global illumination must be solved to cancel this secondary
    scattering. In this paper, we propose a global illumination cancellation method
    that minimizes the perceptual difference between the desired imagery and the actual
    total illumination in the resulting physical environment. Using Gauss-Newton and
    active set methods, we design a fast solver for the bound constrained nonlinear
    least squares problem raised by the perceptual error metrics. Our solver is further
    accelerated with a CUDA implementation and multi-resolution method to achieve
    1–2 fps for problems with approximately 3000 variables. We demonstrate the global
    illumination cancellation algorithm with our multi-projector system. Results show
    that our method preserves the color fidelity of the desired imagery significantly
    better than previous methods.
