局部极大值 meaning in Chinese
lokales maximum local maximum
Examples
- After analyzing the real match position and false match position from the correlation surface , the new method can search the real match position based on the feature of the peak on the correlation surface
由灰度相关计算得到的相关面,通过分析真实匹配位置和虚假匹配位置局部极大值峰的特性,找到了一种基于峰值特征检测寻找真实匹配点的方法。 - In order to find the detecting signal characteristics of all kinds of flaws for ect and ac - mfl , itestablished the signal analysis method based on rectangular flaw , which was validated throughthe experimental research on ect and the emulational research on ac - mfl for different shapeand dimension flaws . the method was explained that a flaw with an arbitrary shape can berepresented as a set of flaws with the simplest rectangular shape . as the synthetic application of these researches , the problem of defect detection of bolt wasresearched
为实现螺纹区域中的缺陷检测,提出了提取局部极大值的缺陷识别方法;并根据位置的不同将缺陷分为螺杆结合部缺陷、螺纹区域缺陷以及螺纹尾部缺陷三类,对每类缺陷的信号特点进行了分析,给出了缺陷检测的判据,并通过实验验证了识别方法的可靠性;最后对螺栓头杆结合部的缺陷检测进行了实验研究,并根据信号特点建立了相应的缺陷检测方法。 - When a smoothing function ' s first derivative is adopted as wavelet function , the local maxima of wavelet transform modulus detect the location of signal ' s singularities , in this thesis , these characters are not only applied to measure the magnitude of dead angles of the dissymmetry inrush but also the symmetry inrush in three - phase transformer
当小波函数取光滑函数的一阶导数时,信号小波变换的模在信号突变点将取得局部极大值。本文利用这些性质不仅对三相变压器的非对称性涌流间断角的大小进行测量,同时还测量了对称性涌流的间断角,测量精度有一定的改善。
