盲区
阴影区
影区
Examples
- The light blue region is a partial shadow region where illumination drops smoothly from full light to full shadow
亮蓝色区域是一个部分阴影区域，照明从完全照亮柔和地过渡到完全阴影。 - Shadow detection was performed in every block based on the illumination invariant between the shadow region and the corresponding background region
对其中的每一块，根据阴影区域和相对应的背景区域之间的光照不变性进行阴影检测。 - The land clutter is useless signals for target detection caused by land terrain . the multipath effect is some kind of interference which is caused by wave reflection on terrain . the diffraction effect is the phenomenon of wave propagation into shadow region
地杂波是由地面散射引起的对目标探测无用的信号;多路径是由电磁波在地面反射所引起的干涉;衍射则是电波绕射传播到遮蔽区的现象。 - In addition combining opengl technology , we can translate the source shape data of targets displayed on the computer screen to the data for rcs computing . " graphical electromagnetic computing ( greco ) " was presented in these conditions , which has many merits such as detecting shadowed regions automatically , computing in real time and accurately and so on
图形电磁计算( graphicalelectromagneticcomputing ， greco )方法就是在这样的环境下产生的，它具有诸如自动实现消隐，计算速度快，精度高等优点，目前被认为是求解高频区复杂目标的最有效的方法之一。 - Secondly , each region ’ s orientation line is calculated to prejudge the regions that contain the shadow regions , and the regions that contain shadow region are marked . thirdly , the marked region ’ s body color vector is calculated , and it is matched with that in the shadow database , after that , the shadow region can be obtained accurately
接着计算前景中每个区域的方向角分割线,预判断每个区域中是否含有阴影区域,标记出含有阴影区域的区域,然后对有标记的区域计算其体色向量,和阴影数据库中的体色向量进行匹配运算,精确定位出阴影区域。
