Fig. 9 — a The virtual illumination function design space and b the corresponding design parameters with reconstructions and their run times. As shown in a, considering the peak ratio γ and the temporal envelope length D = β ⋅ λ (characterized by how many modulation cycles fit inside the envelope) for the illumination function, we plot each corresponding reconstruction and processing time for the Office Scene dataset with 20 ms exposure in b. The peak ratio γ coefficient is used for thresholding in the Fourier domain. Overall, the more Fourier components used during the reconstruction, the better the noise reduction and the longer the calculation time.
