TL;DR
本文提出了一种应用于参与媒体的光度立体方法，通过建模形状相关的前向散射，用查找表描述前向散射，并表示为空间各异的内核，以及通过将大规模稠密矩阵近似为稀疏矩阵，可消除前向散射，实验结果证明该方法在参与媒体下的3D重建具有很好的性能。
Abstract
Images captured in
participating media
such as murky water, fog, or smoke are degraded by scattered light. Thus, the use of traditional three-dimensional (3D) reconstruction techniques in such environments is difficult. In this paper, we propose a
