统计特征值 meaning in Chinese

statistical characteristics

The observed data of temperature during 1954 ~ 2003 in hotan area were used , the annual and seasonal change trends are analyzed by moving - average method ; the statistical characteristics were calculated to analyze the variation feature of temperature within a year
摘要本文采用和田地区1954 - 2003年气温实测资料，使用滑动平均法计算气温年际及季节变化趋势；计算统计特征值来分析气温年内变化特征。
After reviewing wavelet theory , pyramid wavelet decomposition was introduced to texture representation , we discussed the problem of optimal window size for texture feature extraction method ; the problem of local statistical feature value refinement has been studied , and a refinement method has been given which can decrease the boundary effect in calculating the feature value
在叙述小波分析理论的基础上，把金字塔小波分解引入到纹理表示中来，讨论了提取纹理特征值时选取窗口大小的问题；研究了局部统计特征值的改进问题，给出了一种对所提取的纹理特征值的改进算法，一定程度上克服了计算纹理特征时的边界效应。
