noise point meaning in Chinese
噪点
噪音点
Examples
- This paper takes the hough transform to simulate a velocity profile by using the anti - noise advantage of hough transform to eliminate the noise points
利用霍夫变换抗干扰（或噪声）能力强的优点，可将干扰点（或噪声）剔除，然后用霍夫变换拟合流速剖面。 - If a higher accuracy resolution is required , the distances of points to the fitting line can be taken as the judgment standard , and the data eliminated noise points by hough transform can be simulated by the least square method
当精度要求较高时，可将各拟合点到拟合直线的距离作为判别标准，对经霍夫变换剔除干扰点（或噪声）后的数据点再进行最小二乘法拟合。 - It processes these data that gathered from the optical measurement system or other 3d measuring apparatus directly without the preprocessing of wiping off noise points . user can define the resolution of the exported triangle mesh through setting a few parameters . it still can process other information of the points of cloud except for the x , y , z coordinates , such as color information ( rgb )
它可以直接处理来源于光学测量系统或者其他的一些三维测量系统的数据，而不用经过去除杂点的数据预处理过程；输出三角形网格的解析度可以由用户通过设置一些参数来进行控制；这个算法还可以处理一些来自于点云的点所带的除了( x ， y ， z )坐标以外的一些信息，比如说颜色信息( rgb )等；此外我们还提供了几种可以实现的纹理映射( texturemapping )的思路。 - Finally , a new 3d surface ranging method based on a digital fringe projection and shifting technique is systematically studied and non - linear rectification algorithms which reduce measurement error is proposed . at the same time , the noise - immune phase unwrapping algorithm is deeply studied and a new algorithm for phase unwrapping of phase map is proposed . experiment make known the algorithm can reduce measurement error , bypass the noise points automatically , solve the problem of the shade sheltering or cavity , overcome the error propagation problem and better results have been obtained
论文最后系统研究了基于数字相移条纹投影曲面三维测量方法，创造性地提出了一种减小测量误差的非线性校正算法，取得了预期的效果；同时对相位去包裹算法进行了较深入研究，提出了一种噪声图像相位去包裹方法；实验表明该方法能减小非线性测量误差，自动避开噪声点和间断点，获得了满意的结果。 - Then the research of image enhancement based on of plateau equalization algorithm and genetic algorithm is done then in this chapter . image segmentation with algorithm of 2d - maximal variance between - class and region growing is accepted to eliminate the background and the isolated noise points which can not be the target
论文在红外目标检测方面,以对经过预处理的图像进行分割为切入点,采用二维类间方差法和局域生长法来进行图像的分割,消除了原始图像中一些不可能为目标的孤立噪声点和大面积的背景区域。
