Gaussian smoothing

We extend the smoothing methods for 2d image to the field of the range image. Analysing the noise models, we utilize the Median filter and Gaussian filter to do the 3d smooth for the range image.

本文将平面图像平滑的方法拓展到深度图像领域，通过分析噪声模型，我们利用中值滤波器和高斯滤波器对深度图像进行三维平滑。

According to the requirement of beam smoothing in laser systems, the continuous phase plate with Gaussian distribution is designed.

针对激光系统对光束匀滑的需求，设计了高斯型连续相位板，并对其远场特性进行了研究。

Occluded people would be divided into each other by the Gaussian-smoothing histograms. The matching relation of each person in different cameras could be found and thus the human tracking is realized.

在此基础上，依据直方图模型将互相遮挡的人体分割开来，最后根据求取的人体像素点的匹配关系来确定不同摄像机中同一个人的对应关系。
