standard variance meaning in English
标准差
标准方差
Examples
- Embedding is selectively done in 8 x 8 blocks whose standard variance is less than the average of 8 - neighbor connective blocks " , and strength factor is determined by local image contents
水印有选择性地嵌入在那些标准方差小于8 -邻域方差均值的8 8块内，嵌入强度因子由图像局部内容确定。 - In this paper we will discuss two asymptotic normal statistics of normal distribution n ( , ^ 2 ) standard variance and these statistics compare on the principle of relative asymptotic efficency
摘要讨论了正态分布标准方差的两个渐近正态估计量及它们之间的优良性的比较，利用相对渐近效准则作为比较的准则。 - ( 2 ) the response characteristics of wind - induced vibration under uncertain parameters were analyzed , which suggested a simplified method for evaluating mean and standard variance of acceleration responses . compared with the results given by a form and fosm method , the suggested methods can give a more precise estimation
( 2 )研究了随机参数作用下的结构风振均方根加速度响应的分布规律，给出了直接估计均方根加速度响应均值和方差的解析表达式。 - Firstly , basic theory of wavelet transformation and mallat algorithm are introduced . then photothermal images are fused using means of the fusion rules based on selecting larger coefficient absolute value and area - based maximum standard variance . it corrects the disturbance of object ’ s surface status and reduces the influence of object ’ s surface characteristic during infrared detection
首先介绍了小波变换的基本理论及mallat算法,然后利用系数绝对值取大和基于局部方差最大化的融合规则对图像进行融合,修正了物体表面状况的干扰,降低了物体表面特征对红外检测的影响。
