预测算子,prediction operator
Predictor[英][pr?"d?kt?(r)][美][pr?"d?kt?]预测算子
1.SGWT is different from the classical wavelet transform:not relying on Fourier transform (FT),doing all calculation on timedomain, and constructing special property wavelet by designing predictor and updater.第2代小波变换与经典小波变换不同,它不依赖Fourier变换,所有的运算在时域上进行,通过设计预测算子和提升算子可以构造具有某种特性的小波。
3)predicting operator预测算子
1.When construct the lifting wavelet,the methods choosingpredicting operator and updating operator are different.在提升小波的构造过程中预测算子和更新算子的选取不能混为一谈,为了更准确地将信号分解成低频分量和高频分量,提出更新算子的选取标准是各分量的和等于1/2,利用最小二乘法选取预测算子,并将构造出的提升小波运用于信号消噪,进一步研究预测算子和更新算子的选取规律,得到了较好的实验效果,验证了结论的正确性和实用性。
4)Predict operator预测算子
1.The key idea of the lifting scheme is constructing wavelet filters by several predict operators and update operators.由于传统小波的多相矩阵可以分解为多个矩阵的乘积,本文从原理上说明了这些矩阵可以看作是预测算子和更新算子,并给出了具体例子。
5)direction-predicting operator方向预测算子
1.For this purpose,a template matching method based on thedirection-predicting operator of grading 8 neighborhoods is proposed and is then applied to the high-accuracy image splicing of the IC chip.文中针对IC芯片表面形貌图像的获取要求,提出了一种基于分层八邻域方向预测算子的模板匹配方法,并运用于高精度要求的IC芯片图像处理工作中。
