compact wavelet 中文意思是什麼
compact wavelet
解釋
壓縮子波-
The experts in engineering, especially in engineering expect that the compact support wavelets are real, orthogonal and symmetric. in fact, no such a wavelet, except the wavelet haar, is found
工程界使用的小波一般而言是實值的緊支正交對稱或反對稱的，這有很多好處，尤其在數字圖像的邊界處理中。 -
The focus of the paper is divided into two parts : the part one where the compact supported orthogonal wavelet about symmetry is discussed and a new method about symmetrizing wavelet is put
信號的采樣從均勻采樣到不規則采樣是一個很大的進步，給以shannon為基礎的信息論增添了新的一頁。 -
Generally speaking, the regularity of orthonormal wavelet bases with compact support increases linearly with the support width. but if we relax the orthogonality, much more freedom on the choice of wavelet function is gained
一般來說，對于規范正交小波基，它的正則性階數是隨其支集寬度線性增長的，而如果放鬆了正交性要求后，母小波可以同時具備局部支撐性和無限光滑性。 -
The compact support wavelet which is real and orthogonal isdivided into two parts : symmetrical part and anti - symmetrical one. it proves that both the two parts are still made into compact orthogonal wavelet base which are symmetrical and anti - symmetrical respectively. it proves that symmetrical part and anti - symmetrical one of scale function are scale function and wavelet function in some subspace respectively
本文提出一種新的對稱化方法，把一大類緊支集實值的非對稱正交小波函數分解成對稱和反對稱兩部分，並證明了其相應的兩部分仍然構成對稱和反對稱的緊支正交小波基，而且我們發現尺度函數對稱和反對稱部分分別是某子空間的尺度函數和小波函數。 -
Compact in configuration, mightiness in function, convenience in manipulate and high resolution, high efficiency, low cost are all the characteristics of this instrument. in the end, we give a brief introduce about some common analysis methods on oae signal. and lay a emphasis on wavelet and improved wigner - vill used in the analysis of soae and teoae, comparing with the tradition method, these new time - frequent methods have better time - frequent characteristic, are fitter for the oae signals
最後，該文分別對耳聲發射信號的常用分析方法進行了介紹，並重點介紹了用小波變換、改進的維格納分佈等方法分別對soae信號、 teoae信號進行分析的情況，與傳統的處理方法相比較，時頻分析方法由於具有較好的時頻解析度，更適合於耳聲發射信號的分析。 -
Multi - resolution analysis model and view correlation three - dimension terrain display based on biothogonal compact wavelet
基於緊支雙正交小波的多解析度分析模型與視覺相關三維地表顯示 -
Without much theoretical deduction in this dissertation, we focus mainly on the several characteristics of wavelet, such as the localization in both the spatial and the frequency domain derived from the compact support in the two domains ; the rnultiresolution representation property ; and the octave divided frequency property, etc. after a brief overview of the principles and methods of image compression, video coding algorithms are introduced including 3 - d wavelet video coding and 2 - d wavelet video coding. based on the above, the research of this dissertation consists of three aspect : firstly, the 3d - spiht algorithm is modified which optimizes bit allocation
具體說，本論文包括以下內容：首先，本文分析介紹了小波理論，文中沒有過多的理論推導，而是從小波具有的一些特性，如時頻局部性、多解析度分解特性和倍頻程頻帶分解特性入手，力求對小波變換有一個宏觀的了解。其次，介紹了基於小波的圖像編碼的原理和常用的編碼方法。最後，介紹了基於小波的視頻編碼的方法，一種是基於3 ? d小波視頻編碼，另一種是基於2 ? d的小波視頻編碼方法。
