误差分散 meaning in English

error variance

Halftone watermarking algorithm by threshold - altered error diffusion
基于变阈值量化误差分散的半调水印算法
The error diffusion algorithm , first introduced by fioyd and steinberg , requires neighborhood operations . lt is currentiy the most popuiar neighborhood halftoning process . the dithering algorithm , which has been used in era2000 system , is able to prov
误差分散算法是山fioyd和steinberg首先提出的，它采用的是邻域操作，是目前最流行的邻域半色调处理算法。
For the methods based on constraint residual , they can be used to only tell which node is imbalance but cannot identify where the gross error is . in order to avoid these problems , this thesis proposed a new test method . the new method combines an f - statistic with constraint residual statistic to detect gross errors in steady state processes
这种方法即避免了基于测量残差的检测方法会将显著误差分散到各个测量值中去的缺陷；又避免了基于约束残差的检测方法只能对节点的平衡性进行判断，而无法确定显著误差的具体发生位置的缺陷。
