Examples
- Scale value decision method for discrete grid gabor wavelet transform
小波变换的尺度参数取值方法 - Confidence interval for scale parameter of normal distribution from incomplete observational data
正态分布尺度参数基于残缺观测数据的置信区间 - We find that fitness of returns on stocks to non - normal stable distributions in china stock market is very good by fitness test ; study measurements of return and risk of a portfolio conditional on non - normal stable distributions and put forward mean - scale parameter model ; find that mean - scale parameter model can explain asset allocation puzzle by empirical analysis
通过拟合优度检验发现我国的股票收益率与非正态稳定分布的拟合效果非常好；研究了非正态稳定分布条件下投资组合收益和风险的度量，建立了均值尺度参数投资组合模型；通过实证分析发现均值尺度参数模型能够解释资产配置之谜。 - ( 2 ) in the study of multivariate phenomena , each time variable should possess its own scaling parameter in order to allow maximal flexibility in time - frequency . the notion of multifrequency multifunction wavelets , to be introduced , is based on this point of view . multifrequency wavelets , via directional multiresolution analysis , generated by a single function is extended to multifrequency multifunction wavelets generated by a finite number of functions
( 2 )在研究多变量问题时，为了使时频分析具有最大的灵活性，要求每个时间变量都有它自己的尺度参数，鉴于此，本文从尺度函数构成正交基或riesz基出发，把一维多函数小波推广到二维多频率多函数小波，解决了构造正交或双正交多频率多函数小波所需要的理论依据。 - Second , more feature points are extracted for advanced registration based on projective transformation . compared with the ordinary method , our method has a better robust feature with higher accuracy , it also has a fully automatic feature so it need little human intervention in the whole process . the image segmentation , feature extraction , feature correspondency , and transformation model of multi - modality medical image registration are also studied in this paper
本研究的创新之处:针对rf和fa视网膜图像的特点，提出了新的血管细化的新方案;在特征点提取方面，提出了“三轮定心”这种新的特征点提取方法;提出了由“粗配”到“细配”的混合配准方法;力矩主轴法用于图像配准参数的估计及对应性尺度参数范围的定值。
