1) direct-shadow image
阴影图象
2) shadowgraph
[英]['ʃædəu,grɑ:f] [美]['ʃædo,græf]
阴影仪，阴影图象，阴影图
3) "shadowy" phenomenon
"阴影"现象
4) shadow matting
阴影抠图
1.
In this paper, its historical development is at first outlined, followed by a detailed review on the main matting technologies, including blue screen matting, natural image matting, as well as some extended technologies of matting on image, such as environment matting, shadow matting, and video matting.
回顾了该技术的历史发展过程,包括光学场景抽取、蓝屏抠图和图像合成技术,重点介绍了数字蓝屏抠图、自然图像抠图以及数字抠图技术的扩展和应用,如环境抠图、阴影抠图、视频抠图等,并对这几种技术的局限性以及发展方向做了简要的说明。
5) shadow maps
阴影图
1.
Algorithm of real-time soft shadows based on shadow maps;
一种基于阴影图的实时软阴影算法
2.
Variance shadow maps algorithm adopts a probability method to estimate the up-bound of the probability of a pixel falling in shadow,it effectively reduces the aliasing in traditional shadow maps algorithm by filtering the shadow maps themselves.
方差阴影图算法使用概率的方法计算像素被遮挡的上限概率,通过对深度图滤波的方法来有效地减少阴影图算法中的走样问题,但在深度比较复杂的场景中方差阴影图算法会出现光渗现象,即在应该是阴影的区域却有了亮度。
