Cross - correlation method used in get based frequency part and realized balancing function . gao huawei ( mechanical design and theory ) directed by vice - prof 采用互相关原理提取振动信号基频分量,计算振幅和相位,完成了动平衡功能。
Both ratio of average ( roa ) and cross - correlation method use local statistics to judge road . they perform good detection while smoothing speckle . moreover , they both have constant false alarm rate ( cfar ) which is important in radar target detecting 本文所采用的均值比例算子和互相关算子利用图像局部的统计信息进行判决,在检测道路基元的同时对图像进行局部平滑以降低相干斑干扰;并且两个算子都具有恒虚警特性,门限值由给定的虚警概率确定。
