Error Estimation for Many-light Rendering with Supersampling

Abstract: In this paper, we propose a method to improve the estimation accuracy for many-light rendering of visual and illumination effects such as antialiasing, DOF, volumetric scattering and subsurface scattering.

Reconstruction of Volumetric Reflectance using Spatio-Sequential Frequency Correlation Imaging

Abstract: We propose a novel pro-cam technique for reconstruction of the volumetric reflectance inside an object by using spatio-sequentially modulated illumination to extract only the required signal at a 3D point.
