背景反射

Lighting灯光I normally use quite a lot of light sources; I place them so I can highlight details of the scene. In this image I have used 13 lights: 4 omni lights as ambient lighting, 2 to highlight the form of the engine, 3 spotlights to highlight the back of the engine, 3 highlight to stress the specular and the greasy effect on the shell, a spotlight behind the snail neck for the sub surface scattering, in addition to the sun with area shade and the sky with a HDRI with an atmosphere similar to the photograph of the road for the global lighting I have used a surface with an asphalt texture for the floor and the yellow lines only to be reflected on the engine and to add some radiosity to the snail body and shine.

通常我使用很多的光源，我到处放置它们，这样我才能照到足够多的细节，在这幅图里我使用了13盏灯，4 盏点光源作为环境光，2盏来照亮引擎的形状，三盏聚光灯用来照亮引擎的背面，三盏来强调蜗牛壳的高光及油腻的感觉，有一盏蜗牛脖子背后的灯光来表现3S半透明效果，另外还有一盏太阳光来获得各个区域的阴影，以及一个赋予了HDRI贴图的sky，来作为全局光，我使用了一种沥青材质作为地面材质，并让引擎能反射地面上的黄色带子，并为蜗牛身体与光射线增加了一些radiosity，以取得得与背景类似的灯光环境。

Firstly, based on BLOB knowledge, the method transferred 3D color space to 2D angle-mode color space and defined a set of rules of truncated cone to detect shadow BLOB and reflection BLOB. Secondly, the method removed the ghost BLOB from the moving visual BLOB by calculating permanence memory. Finally, the method used a long-time and short-time dual-background model to detect static visual object.

基于BLOB知识，将3D颜色空间变换为&夹角-模差&2D空间后，定义一套圆锥裁剪规则划分出阴影BLOB和反射BLOB；再以一种持久化记忆PM方法判别出鬼影BLOB；最后改进双背景模型检测出静止目标和运动目标。

The proposed localization approach is useful in the presence of background noise and reverberations.

此语者定位方法可以抵抗背景杂音与反射效应，并於近场与遮蔽的环境中提供准确的语者定位结果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
