Non-line-of-sight (NLOS) imaging aims to reconstruct partially or completely occluded scenes. Recent approaches have demonstrated high-quality reconstructions of complex scenes with arbitrary reflectance, occlusions, and significant multi-path effects. However, previous works focused on surface scattering only, which reduces the generality in more challenging scenarios such as submerged media. In this work, we investigate current state-of-the-art NLOS methods based phasor fields We...
We present an unbiased numerical integration algorithm that handles both low-frequency regions and high-frequency details of multidimensional integrals. It combines quadrature Monte Carlo by using a quadrature-based approximation as control variate the signal. adaptively build constructed piecewise polynomial, which can be analytically integrated, accurately reconstructs integrand. then recover missed residual. Our work leverages importance sampling techniques working in primary space,...
