A digitized harmonic detection method based on resampling and feedback theory is proposed. 提出了基于重采样和反馈理论的数字化谐波检测方法。
In this paper, we presented theoretic analysis and experiment research in pixel resampling, pixel reassigning and weight coe fficient selecting. 本文对任意剖面显示过程中象素的重采样，象素的重赋值，以及加权系数的选择三个方面做了理论分析和实验研究。
While retesting refers to analysis of the original sample, resampling involves analyzing a specimen from the collection of a new sample from the batch. 涉及最初样品分析的再检验，再取样包括从该批产品抽取新的样品。
But resampling in the frequency domain will causes replicas occur in the spatial domain if we do not use any reconstruction filter. 但是它会有频域空间再取样的问题，导致重叠影像的失真现象，因此滤波器的设计对傅立叶立体资料描绘法是非常重要的研究主题。
