local weighting meaning in English
局部加权
Examples
- These pages can be divided into two classes : one is relevant pages r , another is unrelevant pages r . taking use of the difference of local weight between r and r , we choose the term with most difference as character term
利用术语在r和r中的局部权重的不同，选择权重差别最大的那些术语作为特征术语，以确定和调整向量空间的维度，在降低向量空间维度的情况下，尽量保持模型的准确性。 - Then the local weighted mean method is used to register the image distortions . this method can not only successively register the local geometric distortions but also fit for the infinite length image registration . images are registered and exported with sequential subsections
然后以局部加权平均的表面拟和方法对失配图像做几何校正，该方法既有效地校正了遥感图像中的局部几何畸变，又适合于针对无限长图像进行数据流式的分段配准输出。 - Two - stage - fitting ( tsf ) method is obtained , which consists of evaluating the function values of regular - grid points by using local weighted least square methods or radial function interpolation , and smoothly and quickly interpolating those points by using multivariate splines . the result is a hyper - surface of c1 or c : continuity
基于上述结果，提出了h - d空间散乱数据超曲面构造二步法，第一步应用局部最小二乘法或局部径向基函数拟合法插补立方体网格点上的函数值，第二步应用多元样条光滑快速插值计算，使所得超曲面具有c ~ 1或c ~ 2连续。 - For h - d scattered data , local weighted least - squares fitting ( llsf ) methods for approximation and interpolation are respectively put forward and the latter is got by adjusting weight function in the former case , and the interpolating method is also used to construct hyper - surface models with the radial function . the problem of choosing weight function during local least square approximation is discussed and two good weight functions are given : one with a parameter , the other with no parameter . based on them
二、对非规则区域上分布的h - d数据，提出了散乱数据超曲面拟合的局部最小二乘逼近法。通过对局部最小二乘逼近的权因子作适当的改进，得到了拟合精度较高的局部最小二乘插值法，还用径向基函数构造了超曲面模型，找到了一种性质好带参数的权函数以及另一种有着普遍精度性质的不含参数的权函数，获得了较好的逼近效果。
