population dispersionとは 意味・読み方・使い方

As regarding the plurality of temporary outline data detected by the outline detection means 2 as a population, an arithmetic means 3 detects the dispersion of a plurality of first distances between the plurality of temporary outline data and the centroid of the population, and computes a plurality of second distances between the centroid of the detected dispersion and the plurality of temporary outline data, and also the average of the plurality of second distances.例文帳に追加

演算手段３は、輪郭検出手段２によって検出された複数の仮の輪郭データを母集団としたときの複数の仮の輪郭データと母集団の重心との複数の第１の距離のばらつきを検出し、その検出したばらつきの重心と複数の仮の輪郭データとの複数の第２の距離と複数の第２の距離の平均とを演算する。 - 特許庁

Statistic μ and σ^2 and an improved mean value μ_m of ultrasonic receiving signals corresponding to respective first ROIs (Region Of Interest) set in a second ROI, or an analysis region, are calculated and a dispersion value σ_0^2 of a virtual population is estimated using them.例文帳に追加

解析領域である第２ＲＯＩ内に設定された各第１ＲＯＩに対応する超音波受信信号の統計量μ、σ^２、改良平均値μ_ｍを計算し、これらを用いて仮想的な母集団の分散値σ_０^２を推定する。 - 特許庁
