Firstly , human skin - color information is used to segment images into skin color region and non - skin color region , then pretreat the skin - color region and come into the phase of image similarity 首先利用彩色图像的颜色信息把彩色图像分割成肤色区域与非肤色区域，然后对肤色区域做预处理后，进入图像似然度检测阶段。
Test - retest reliability , split - half reliability , internal concordance coefficient ( cronbach a coefficient ) , content validity , construct validity and index validity of the mental self - supporting questionnaire of university students were good 对自编的《大学生心理自立问卷》进行了尽可能多角度、多指标的信效度检测。
Considering that the way to gain standard maximum dry density value of xigeda filling is complex , this paper suggests adopt means combining field cbr test and compactness measuring to control construction quality 鉴于昔格达混合填料标准最大干密度取值的复杂性，建议采用现场承载比与压实度检测相结合的办法进行现场施工质量控制。
The paper briefly reviews the use of rebate rules in validity tests of the contingent valuation method , a survey method widely used to estimate the value of natural resources under realistic , but hypothetical , conditions 本报告简要回顾退还规则之应用在条例评估法的效度检测，这是在真实但假设条件下，广泛用来评估自然资源价值的一种调查方法。
