Dissemination and application of the maximum module 最大模原則的推廣及應用
Fast algorithms of both discrete and orthonormal wavelet and wavelet packet coefficient are diagrammatized to be introduced . daubechies wavelet is applied to help to discuss the application and test on signal filtering and noise reduction with the principle and threshold implementation; the basic principle to pickup the fault characteristics is introduced mainly about the relations between the maximum module and signal saltation point and how to characterize the saltation point with lipschitz exponent 展示了離散正交小波變換的mallat快速算法和小波包系數(shù)分解的快速算法;重點應用daubeches小波探討了小波變換在信號濾波去噪中的應用和實驗,闡述了其基本原理和通過閾值化處理實現(xiàn)濾波的具體方法;探討了用小波變換進行故障特征提取的原理,說明了小波變換模極大值和信號突變點之間的關系以及怎樣用李氏指數(shù)來表征突變點的性質。
A theory using image local maximum modules, got by wavelet transform, as image feature, is promoted and proved well . finally, using image mosaic technique based on multi-resolution analysis, redundancies between images are eliminated . the whole image produced at last is a much bigger one without seam and distortion 提出了圖像邊緣局部最大模作為匹配特征的理論,并取得很好的效果;最終通過多分辨分析圖像融合技術消除圖像間的冗余,并把它們合成為一幅無接縫、無畸變的、大區(qū)域圖像。
