波譜特徵空間By choosing some appropriate exponential weight functions we prove that the essential spectra and the eigenvalues ( except the simple zero eigenvalue ) have negative real parts, thus we get the locally asymptotically exponential stability of travelling waves ( al ) and ( a2 ) in some weighted spaces
通過選用合適的權函數,我們證得在加權空間線性化運算元的本質譜和除簡單特徵值零以外的特徵值均具有負實部。因此,我們得到行波( a1 ) , ( a2 )在加權的l ~ 2 ( r )空間的局部漸近指數穩定。For viscous shock waves c, by the spectral analysis we prove that in l2 ( r ) space the essential spectra and the eigenvalues ( except the simple zero eigenvalue ) of the linearized operator have negative real parts, thus we show that the viscous shock waves c is locally asymptotically exponentially stable in l2 ( r ) space
對粘性沖擊波c利用類似方法,我們證得在l ~ 2 ( r )空間線性化運算元的本質譜和除簡單特徵值零以外的特徵值均具有負實部。於是,我們得到粘性沖擊波c在l ~ 2 ( r )空間的局部漸近指數穩定。First, the thesis introduces the definitions and the attributes of the higher - order statistics. it is insensitive to additive gaussian noise ( white or colored ), which is what we base on to doa problems. then two doa estimation algorithms based on higher - order statistics are presented, one is that forming cumulant matrix pencil used in esprit to estimate doa problems, the other is spectrum estimation method for doa estimation based on the eigenstructure analysis of the fourth - order cumulant, and comparing the effects of the estimation to conventional covariance - based doa algorithms "
論文首先對高階統計量的定義和性質作了介紹,特別指出了高階統計量對加性高斯噪聲(白色或有色)不敏感,這是我們利用它進行波達方向估計的理論依據,然後文中提出了兩種基於高階統計量的波達方向估計方法,一種是利用子空間旋轉不變技術構造四階累積量矩陣進行估計的方法,另一種是基於四階累積量陣特徵分解的空間譜估計測向方法,並將它們的估計效果與傳統協方差方法的效果進行比較。The analysis and discrimination of spectral reflectance for grassland vegetation on different spatial scales
內蒙古草原不同空間尺度的植被反射波譜特徵分析與鑒別Hyperspectral images consist of one - dimension spectrum and two - dimension space information. they are wildly used in resource exploration, environmental inspection, military detection, geographic prospecting, and so forth. besides the properties of common remote sensing images, the much greater number of spectrum bands and the higher spectrum resolution are the unique, hence the larger data quantity
高光譜圖像包含一維光譜信息和二維空間信息,在資源探測、環境監視、軍事偵察、地質勘探等眾多領域得到了廣泛應用,除了具有一般遙感圖像的特徵同時,它的波段數目更多,光譜解析度更高,因而其數據量更為龐大。Investigation using remote sensing ( rs ) technology can breakthrough the limits of traditional methods, make full use of its capability of integration, visualization, rapidity and vast - dimensions analysis, and get better results the paper takes the up - to - date landsat - 7 etm + data, which is the most widely used, and quickbird data, which has the highest resolution nowadays, and according the features of the data and landslides, processes the quickbird data with 1 : 10 000 dem orthophoto correction and the landsat - 7 etm + data as follows : ( 1 ) selecting optimal spectrum band : selects 753 bands as the optimal bands ; ( 2 ) image intensifying : selects the principle components processing method on the basis of comparing several image intensifying methods ; ( 3 ) rigour geometric direction : corrects the geometric distortion of the map ; ( 4 ) image fusion : mainly takes his space transform fusion and resolution fusion method, and acquires maps with higher spectrum resolution as well as space resolution. after that, the visual effect of the image has been enhanced, and the interpretation precision
採用遙感技術,可以突破傳統調查方法的限制,發揮其宏觀、綜合、直觀、快速的特點,取得更好的效果。論文選取目前應用最廣的陸地衛星最新系列landsat - 7etm +數據和空間解析度最高的商業衛星quickbird數據作為主要的數據源,根據數據的特點及滑坡災害應用特徵,對quickbird遙感數據則基於1 : 10000dem進行了正射校正,對etm +遙感數據進行了波段優選,選取了753作為最佳組合波段;圖像增強,通過各種增強處理方法的效果對比,選擇主成分分析法對圖像進行增強;幾何精校正,糾正圖像的幾何變形;影像融合,主要選取了效果較好的his空間變換融合和解析度融合,得到的圖像既具有較高的光譜解析度,同時也具有較高的空間解析度。經過上述數字處理,較好地改善了圖像的視覺效果,提高了圖像解譯的精度。This scheme covers techniques of texture analysis, synthesis, texture mapping and 3 - d knitting pattern analysis of fabric. we discuss here the techniques related to texture. texture analysis uses frequend - domain, wavelet or mrf to get feature distribution of texture image, classes of texel and the rule of placement
