discrete regions
解釋
分散區-
Thus the areas of the overlapping regions are compensated efficiently and the accuracy of measurement is highly improved. the volume of the bubbles can be estimated on the bubbles " area information, and a genetic algorithm ( ga ) based method is used to match and track bubbles in the image sequences, which solve tracking problem under complex conditions efficiently, such as some bubbles may have kinetic occlusion and crossover, some newly generated bubbles may entered into flow field and run away. a smooth kinetic locus is obtained by fitting the discrete centroids with a cubic spline function and at the same time the visual measurement is realized
根據氣泡在圖像平面中的面積估計氣泡的體積，並對流場中的所有氣泡採用遺傳演算法進行最佳的匹配跟蹤，有效地解決了氣泡群在流場中出現如遮擋、交又、新它『出現、逃逸等復雜情況下的準確跟蹤，並採用三次樣條插值方法對離散的質心點軌跡進行擬合，得到氣泡在流場中平滑的運動軌跡，從而實現了摻氣水流特性的可視化測童。 -
The result indicated that the nadph - dstained neurons and fibers were found in discrete regions throughout the snake brain, such as cerebral hemisphere, supraoptic nucleus, paraventricular nucleus, subcommissural organ, medial longitudinal fasciculus, periventricular grey, locus coeruleus and mesencephalic reticular formation
結果表明：陽性反應主要位於腦的大腦半球、視上核、室旁核、聯合下器官、內側縱束、室旁灰質、藍斑以及網狀結構等區域，比較討論了與其他脊椎動物的異同。 -
Both absolute difference and relative difference among per capita gdps of 14 cities ( prefectures ) increased year by year since 1990 - the absolute difference increased linearly - - and this increased tendency would n ' t change in short period. by counting the discrete and ratio between per capita gdp of every city ( prefectures ) and that of the total province, the relative development speed of every region and the industrial structure of every region, i think that the characteristic of the spatial structure of regional economic difference in hunan is that the area along the beijing - guangzhou railway line in the east of hunan developed fast, while the vast area in the west of hunan developed slowly, so the regional difference increased constantly. on the difference background between the east and the west of hunan, there is the difference between central region and fringe region, for one thing it shows ring difference, namely chang - zhu - tan internal ring, surrounding chang - zhu - tan medium ring, the outermost external ring, the most underdeveloped counties lie on the fringe and mountain regions in the west, south and east of hunan, for another it displays that the peripheral regions of 13 prefectural cities are more developed than the other
文章還建立了反映基礎設施水平、經濟發展水平、社會發展水平的23個主要指標構成的湖南省區域差異衡量指標體系，在此基礎上，藉助spss統計分析軟體，運用主成分分析法，對湖南省14個市州經濟發展綜合水平的差異狀況進行了研究，結果表明：長沙市的經濟發展綜合水平在14個市州中遙遙領先，反映了湖南省經濟發展空間結構的「單極主導」特徵；通過計算人均gdp的標準差和標準差系數，研究區域經濟差異的總體水平及區域經濟不平衡發展的演變趨勢，發現90年代以來湖南省各市州人均gdp的絕對差異和相對差異都在逐年擴大，其中絕對差異隨年份直線上升，且這種差異擴大的趨勢在短期內難以改變；通過計算各市州人均gdp與全省人均gdp的離差和比率、各市州發展速度的差異及產業結構的差異，認為湖南省區域經濟差異的空間特徵是：湘東京廣沿線地區基礎較好，發展較快，湘西地區發展緩慢，地區差異不斷擴大；通過以縣為對象的差異研究發現在湘東湘西差異的大背景上還有核心區與邊緣區的差異，它一方面表現為長株潭內層、圍繞長株潭的中層、更遠的外層的圈層差異特徵，最落後的縣分佈於湘西、湘南、湘 -
The states of the art of dvd protection are described, and two protocol ( cprm and dtcp ), which is proposed by w09 group, are introduced. a novel fragile watermarking approach and related tamper detection are proposed. taking still image as an example, the watermark are embedded in the discrete wavelet domain of an image, so tamper detection is possible in localized spatial and frequency regions
第7章探討了水印演算法設計與水印應用系統設計間的區別，指出水印系統的實用性不僅僅取決于技術上的完善，同時也需要具有完備的協議；提出了一種二維偽隨機序列的產生方法；討論了影響水印系統性能的主要因素及解決方法；舉例說明了完整水印系統的設計過程並嘗試提出了一種完整水印系統協議。 -
A semi - discrete form of our scheme is also presented. this new reconstruction is a third order accuracy in smooth regions and non - oscillations at cell interfaces. our scheme enjoys the main advantage of the central schemes - simplicity, namely it does not employ riemann solvers and hence the intricate and time - consuming characteristic decomposition are avoided
本文針對一維雙曲型守恆律的初值問題，研究了二階和三階中心差分格式，提出了一種改進的三階中心差分格式及其半離散形式，主要是引入了一種新的重構，並證明了這種重構在光滑區域具有三階精度且在網格邊界無振蕩，所提的格式保持了中心差分格式簡單的優點，不需要求解黎曼問題，避免了復雜且耗時的特徵分解過程。
