mahalanobis distance meaning in English
马哈拉诺比斯距离
马氏距离
Examples
- Mahalanobis distance based facial expression recognition
距离进行人脸表情的识别 - At the same time , we consider the reconstructed ermrs of a test sample in two spaccs : the between - class eigenmotion subspace and the within - class eigenmotion subspace , which are used as the classifier rule , in contrast to the traditional methods such as euclidean distance or mahalanobis distance in one subspace . experimental results show that this method outperforms the eigenface method in the presence of facial expression variations
在特征运动的基础上，我们还提出了同类特征运动空间和异类特征运动空间两个子空间的概念，并且分析测试样本在这两个子空间的重建误差，以此作为分类标准，而不是简单地考虑在一个子空间里欧氏距离或者马氏距离。 - It researches the background model based on gradient and chromaticity which can update background in real - time , which provide exact information of objects to next module . in tracking objects module , the thesis applies kalman filter to estimate and predict the objects ’ moving state . in association module , the mahalanobis distance is utilized to get the similarity among objects . “ matching matrix ” is presented to get the best matching object
研究了基于色度、梯度建立背景模型检测目标的方法,能实时更新背景模型,基本避免场景中光线变化的影响,有效消除了目标阴影,能准确检测目标,并得到目标轮廓及提取视频目标,为下一阶段针对目标区域的处理提供较完整的目标信息。
