This graph shows the number of messages that were in the database I was running a test on, plotted over time. I added in a logo, a drop shadow effect, and a stats table of the test run.
图 7是一个线图，显示了测试的数据库中的一些信息，添加了一个徽标、阴影效果和测试的统计表。
The distribution of improved LBP texture is discussed and a significant test is performed to classify each moving pixel into foreground object or moving shadow according to this theory.
通过分析阴影的物理模型，得出局部纹理的光照不变性，利用基于比值判决的LBP纹理法来区分运动车辆和阴影，并应用亮度约束和几何启发式准则进一步改善阴影检测效果。
The key techniques of the rendering of vector data over 3d terrain based on stencil shadow volume algorithm are detailed and the effectiveness of this method is test-proven.

To test which areas are in light and which are in shadow, you can cast a shadow with a pencil on the object.
注意中央光和高光的位置是不一样的。明暗交界线是物体从亮部转入暗部的区域。这个就是光线和表面相切。
