particle weight meaning in Chinese

粒子量
粒子重量

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。
