statistic hypothesis meaning in Chinese
统计假设
Examples
- Based on the model , we develop a cascading segmentation algorithm to separate the sar image into regions , so that each of these regions can be described by one of the single models . several sub - algorithms are developed for the cascading segmentation : the homogeneous region segmentation algorithm based on statistics hypothesis test , the line - like region segmentation algorithm and the strong scatterer segmentation algorithm
根据这些模型，建立了层次式的分割算法，将sar图像分割为若干个可以用单一模型描述的区域；设计了具体的分割算法：基于统计检验的平稳区域分割算法，强散射中心分割算法和线状区域分割算法。 - 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。
