central moment

基本解释

Image edge is detected by the third central moment of its immediate pixel neighborhood.
利用像素邻域的三阶中心矩，可以提取图像边界。
The technical definition of variance is the random variable's second central moment, the weighted average of the square of the differences from the expected value.
3方差的专业定义是随机变量的二次中心矩，与期望值之差的平方的加权平均值。
Maker-matching method used in automatic joint, while morphologic filter and fourth central moment method are used in wiping blue. These methods improve the efficiency and the quality of drawing input.
采用标记匹配方法实现自动拼接，采用形态学滤波和四阶中心矩方法实现不均匀背景图纸的的消蓝，提高了图纸输入的效率和质量。
