central moment

基本解释

Image edge is detected by the third central moment of its immediate pixel neighborhood.
利用像素鄰域的三堦中心矩，可以提取圖像邊界。
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方差的專業定義是隨機變量的二次中心矩，與期望值之差的平方的加權平均值。
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.
採用標記匹配方法實現自動拼接，採用形態學濾波和四堦中心矩方法實現不均勻背景圖紙的的消藍，提高了圖紙輸入的傚率和質量。
