Robust face landmark estimation under occlusion ICCV’13 http://www.vision.caltech.edu/xpburgos/ICCV13...不能够对 outliers 给出一个系统的解决方案，我们提出了一个 Robust Cascaded Pose Regression (RCPR) 来解决这些问题 3.2.1 Robustness to occlusion
SSDO 全称 Screen Space Directional Occlusion，可以看做一种实时 GI 算法，是 SSAO 的升级版。...Ambient Occlusion (AO) 即环境光遮蔽是一种常见的提升表面细节的技术，基本思路是在 Mesh 表面预计算周围的遮挡信息，然后在计算光照的时候把遮蔽因子作为系数叠加到环境光上。...于是 SSAO (Screen Space Ambient Occlusion) 应运而生，在屏幕空间进行计算，在开销可以接受的情况下支持动态场景。

我们还创建了一个大规模的合成数据集Occlusion-Person，它允许我们对被遮挡的关节进行数值评估，因为它为图像中的每个关节提供遮挡标签。
