  3. Visual analysis of human motion has been receiving increasing attention from researchers in the fields of image processing and computer vision during the past few years. it has a lot of applications in virtual reality, smart surveillance system, advanced user interface, motion analysis and video compressing, etc. this paper focuses on the technology of human motion tracking based on video, first, we make a summarization of the domestic and overseas status of the research in this field. on the basis of this, we analyse the technical difficulties of human motion tracking. as most of the existing model - based methods of human motion tracking perform not so good in some situation as they need mannual intervention, and also the precision of tracking is not so satisfying during the research of tracking of walking people because of the self - occlusion of legs, this paper proposes an algorithm of automatic detection and tracking of legs of the walking people based on monocular image sequences, in which we analyse the features of walking people, track the five joints of lower limbs, get various parameters, and then re - construct the walking process. the main research achievement is as follows : 1 ) we propose an algorithm of markerless automatic extraction of leg skeleton. first we divide the video into continuous image sequences, after background subtraction, the satisfying human region could be extracted, then we get a single - connected region by converting the rgb image to binary image and median filtering. afterwards, the contour of lower limbs in the frame with a widest boundingbox is detected, using sobel operator, to find the ankle joint of leg behind according to the features and rules of walking, then, the joint of knee of leg behind, hip, ankle of leg in front, knee of leg in front could be got in turn. so, model of leg skeleton is constructed

    首先將視頻分解成許連續的靜態圖像幀,經過背景去除,把感興趣的人體區域提取出來,通過二值化,中值濾等預處理方法得到只有人體的一個單連通區域,然後用sobel運算元檢測出boundingbox最寬幀中人體下半身的輪廓,根據運動規律及特徵找到後腿踝關節點,結合從boundingbox最窄幀中所獲取的腿得到後腿膝關節,跨部關節,前腿踝關節,前腿膝關節四點,從而構建出腿部骨架模型。 2 )實現了人體步行腿部骨架的跟蹤演算法。在完成對腿部骨架模型的自動初始化之後,本文對跨關節、膝關節及踝關節分別採用運動建模、圓周相交定點演算法、運動預測及預測點周圍搜索rgb相似矩形塊三種方法確定每一幀中其實際坐標,從而重構出腿部骨架的運動過
  4. According to the raman selection rule and the pl measurement, it is reasonable to evaluate the quality of galnp / algalnp mqw by analyzing the relative intensity ratio of a1p - lo / to. ( 4 ) a new modified random element isodisplacement ( mrei ) model is set up to calculate the dependence between the long - wavelength optical phonon frequencies and the composition of iii - v - type ab1 - xcx mixed crystals. the second neighbor force constants are still assumed to be a linear variation with the composition, but the two first neighbor force constants can be evaluated to be a negative exponent variation with the composition, using the overlapped repulsive potential of the ion crystal combination

    通過實驗我們找到了在這些結構參數上生產gainp algainpmqw的較理想的結果; ( 3 )首用喇曼( raman )散射方法研究了常溫下的gainp algainp量子阱結構,除了指認出喇曼光譜中各光學聲子模外,還結合樣品光致發光譜的測量結果,分析發現喇曼光譜中alp - lo to的相對強度比可以在一定度上評定晶體gainp algainpmqw的生質量; ( 4 )在修正的隨機元素等位移? mrei模型的基礎上建立了一個新模型,計算了ab _ ( 1 - x ) c _ x型?族半導體混晶的光學聲子模頻率的組分變化關系。
  5. Finally, for the multi - wavelength backward pumping fra problems, which are very hard to cope with, we proposed multi - dimension parallel shooting method. the simulation results demonstrate that this method is very useful in solving the raman coupled equations, which are representative of the highly nonlinear problems. the shooting can be converged in short time ( the shooting deviation can be less than 10 - 8 after 6 shooting when there are 8 pumping wavelengths )

    最後,對于最難求解的後向泵浦fra問題,本文提出了維并行打靶思想, matlab下數值模擬證明,該維并行打靶法非常適合求解拉曼耦合方這類高度非線性的問題,打靶過收斂速度較快(八泵浦時只需打靶6就可以使打靶偏差小於10 - 8 ) 。
  6. Under the planned economic system, the economy was affected greatly by the plan - makers, as result, the objective laws of economic growth was disturbed and twisted to a large extent, leading to economic growth turning up and down wildly for many times

    在計劃經濟體制下,經濟的總供求受計劃制定者主觀意志的影響很大,經濟動的內在規律性受到很大度的干擾和扭曲,經濟增出現大起大落的局面。
  7. Finally, we study the ( 2 + l ) - dimension nonlinear dispersive long wave equation skillfully, we find the self - transformation between the two equations and turn the ( 2 + l ) - dimension nonlinear dispersive long wave equation into a simple ( 2 + l ) - dimension pde. then, with the homogeneous balance method we obtain the hopf - cole transformation between the ( 2 + l ) - dimension pde and the heat equation. through it, we obtain abundant exact solutions of the ( 2 + l ) - dimension nonlinear dispersive long wave equation with the matlab, including the multi - solitary wave solutions
