中文摘要
本文介紹斷層攝影術的基本原理以及其除雜訊的方法。我們首先將以等斜率斷層掃描演算法取代傳統的影像重組方法,之後我們提出兩種除雜訊的方法:總體經驗模態分解法與維納濾波器,並將其組合運用。最後定量分析這些方法除雜訊效果。
Abstract
This thesis introduces basic principles of tomography and its denoising methods. First, we replace traditional image reconstruction method with equally sloped tomography algorithm (EST). Then, we suggest two ways of denoise, Ensemble Empirical Mode Decomposition (EEMD) and Wiener filter, and combine them to use. Finally, we will analyze their denoising effect quantitatively.
