estimate of standard deviation 中文意思是什麼
estimate of standard deviation
解釋
標準差估計-
We shall use the standard error of estimate as a tool in the same way that we can use the standard deviation.
同標準差一樣，應該把估計值平均誤差當作一個工具。 -
Two indexes was calculated to estimate the best bands union for color combination, one is optimum index factor ( oif, the sum of standard deviation divided by the sum of correlation coefficient. ), the other is the determinant of the co - variance matrix. it can be seen from the result that for color combination the original optimal bands were tm 4, 3, 7 and tm 4, 3, 5, the best mixed images were mnf1, br and ndvi
以協方差矩陣行列式值和最佳指數值（組合波段標準差之和除以相關系數之和）為評價標準，得出對于tm原始波段而言，最佳的彩色合成組合是tm4 、 3 、 7和tm4 、 3 、 5 ；綜合幾種變換圖像的彩色合成的最佳組合是mnf1 、 br 、 ndvi 。 -
In this method, the principal axes method is used to estimate the parameters of the transformation, then with the estimated pamameters as the initialization of powell optimization method and with all of the available information as the feature, a high accurate registration is achieved by calculating the minimum standard deviation between the registered images
該方法首先採用主軸法對變換參數進行初步估計，之後採用powell最優化演算法，利用全圖像灰度信息來作為圖像的參考特徵，通過計算配準圖像之間差的平方和的極值來實現圖像配準，從而提高了配準精度。 -
It can be seen from the measuring results that the deviation is litter than 10. 1 % when the estimate value of the nature radiation ' s kerma is compared to the average value gotten by standard ionization chamber, and the deviation is less than 16. 2 % when the estimate value of two groups of tlds those measuring radiation in laboratory is compared to the conventional true value in standard radiation field
從參比單位給出的測量結果看出，天然環境輻射比釋動能測量的評定值與標準電離室測量的平均值比較，其偏差好於10 . 1 % ，實驗室射線照射組兩組熱釋光劑量計（ tld ）測量評定值與標準輻射約定真值偏差好於16 . 2 % 。
