分段平均 meaning in Chinese
segment average
Examples
- The two parametric methods are proposed to characterize the self - similarity properties , and mainly used to estimate and analyze the hurst coefficient . and the variance of hurst coefficient on the different scales is discovered . also , the visible fractals of portrait figure are studied by extending the one dimension wavelet transform into two dimensions and this will provide a relatively reasonable reference to the parameter estimation of fractals in two dimensions
在对dna序列分形特征作进一步研究方面，首先用小波变换和分段平均傅立叶频谱法对其自相似性和长程相关性进行检验，紧接着用r s分析法和基于小波的间接估计方法对其分形参数即hurst系数进行了估计和比较分析，发现在不同尺度下hurst系数不一致，并且针对portrait图所表现出的明显的分形特征作了进一步研究，把一维小波变换推广到二维，为二维信号的分形参数估计提供了一种较为合理的参考。
