矩形窄縫流道流動過冷沸騰起始點的實驗研究A new waveguide made of changing a wide wall of a rectangular waveguide to a uniform curved wall is called conformal waveguide. a kind of expression of approximate solution for domain mode of the new waveguide, including symmetric, unsymmetric arc, parabolic arch, hyperbolic arch, elliptic arch, etc., is constructed by using boundary condition of mental waveguide, variational method and boundary element method. by using the equivalence principle, an approximate calculating formula for equivalent resonant conductance of a narrow longitudinal halfwavelength slot cut in the curved wall of the unsymmetric arcrectangular waveguide is derived, and the result is shown. although this solution is approximate, it can solve the problem in designing the slotted antenna of such conformal waveguide

首先將視頻分解成許多連續的靜態圖像幀,經過背景去除,把感興趣的人體區域提取出來,通過二值化,中值濾波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長依次得到後腿膝關節,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程。A design method of the dielectric - covered slots arrays in the narrow face of a rectangular wave - guide is presented in this paper
