fourier component

基本解释

The decaying DC component is filtered in the Fourier algorithm, which improves data precision and simplifies hardware circuits.
并采用滤除衰减直流分量的傅氏算法，提高了数据精度、简化了硬件电路。
This paper proposes a new Fourier shape descriptor integrated with Principal Component Analysis(PCA) and the Farthest Point Distance(FPD).
提出一种将主成分分析（PCA）与最远点距离（FPD）相结合的二维形状傅里叶描述子。
In this paper two methods of eliminating decaying DC component from Fourier algorithm are proposed, one for unrecursion Fourier algorithm and the other for recursion, which can be of any data windows.
提出了一种从不同数据窗的非递推富氏算法中消除衰减非周期分量影响的新方法。
