bhattacharyya meaning in English
巴塔查里亚
Examples
- 5 . anew feature extraction algorithm in kernel space is proposed , which uses the bhattacharyya distance as its criterion function
T根据高维核空间的性质，提出了基于bhattach叩a距离准则的核空间特征提取算法（ bgye ） 。 - Furthermore , bhattacharyya distance is employed to estimate the similarity between the target model and each hypotheses of the particle filter , which makes the measurement matching and samples ' weight updating more reasonable
利用巴特查理亚距离描述粒子与目标颜色模型的相似性，作为粒子更新权值的有力依据。 - Bhattacharyya np , basu p , das m , et al negligible male gene flow across ethnic boundaries in india , revealed by analysis of y - chromosomal dna polymorphisms [ j ] . genome res . 1999 aug ; 9 ( 8 ) : 711 - 9
李冬娜、应大君、区采莹，等.中国海南岛黎族人群y染色体上四个微卫星基因座的多态性研究.中华医学遗传学杂志[ j ] . 2003 ; 1 : 1 - 3 - The data is nonlinearly mapped into high dimensional kernel space at first . then a set of feature vectors can be found such that the bhattacharyya distance of the classes mapped into lower dimensional feature space by feature vectors is maximized . thus the upper
该算法采用核函数把样本非线性映射到高维核空间，在核空间中寻找一组最优的特征向量，把样本线性映射到低维特征空间，使类别之间的bhattach删a距离最大，从而使特征空间中样本的baycs分类误差上界最小。 - In the process of evaluating particle weight , in order to distinguish the different color features of the objects , the original algorithm ( evaluating through bhattacharyya distance ) was improved . only the color distribution of the foreground pixel in particle area after the background modeling is counted , therefore the accuracy and efficiency of target tracking are increased
在评价粒子权值时,为了较好的区分目标之间的颜色特征,对原有的用bhattacharyya距离评价的算法进行了改进,仅统计背景建模后粒子区域前景像素的颜色分布,从而提高了目标跟踪的精度和效率。
