噪声阈值 meaning in Chinese

noise threshold

Firstly , a fourth - orders statistic hypothesis testing in inter - frame difference is used to automatically separate the moving areas from the background in a general video sequence . secondly , change areas are extracted as markers of the corresponding moving object . using the marker , region - growing algorithm can locate the precise boundary of moving object
( 3 )基于轮廓跟踪；首先介绍了提取初始模板方法?基于高次统计的判决算法，通过选择合适的背景噪声阈值，最终得到较好的结果，然后对于后续帧中的边界提取，提出将灰度图像所使用的区域生长方法进行改进，即将它们运用到彩色图像中，通过选择合适的生长规则，得到较好边界图。
