直邊花鍵與鋸齒形花鍵規范The author first introduces several problems that interlaced video suffers from : the basic vertical resolution is inadequate for displaying filmlike quality, and interlaced video generates visual artifacts, including edge flicker, shimmering, and diagonal jaggedness. then the author reviews some representative de - interlacing algorithm that has been proposed
論文首先介紹了隔行電視存在的若干個缺陷：對于顯示類似於電影質量的圖像而言，隔行電視的基本垂直解析度是不夠的；隔行電視還會產生許多視覺虛像，例如邊沿閃爍、爬行和鋸齒等，接著簡單回顧了學術界已經提出的經典的去隔行技術。Start directly from the actual shape of gear tooth, taking the similarity theory as a base, and by means of sampling calculation of boundary element and analysis of three elements regression, the simplified formulae for calculation of tooth root stress were established
摘要直接從輪齒的實際形狀出發，以相似理論為基礎，通過邊界元采樣計算和三元回歸分析，建立齒根應力計算的簡化公式。Firstly, the paper introduces the development and application of computer graphics & image technique, discusses the principle and method of cg and digital image processing, such as matrix of the graphic transformation, homogeneous reference frame, sampling and quantization of the image, file format of the image, template operation, etc. secondly the paper introduces the purpose and method of image enhancement processing, explains the each occasion of those methods such as threshold transformation, smoothing processing, sharpening processing, analyzes and contrasts the processing results of object image. thirdly, the paper introduces the method of mathematics morphologic, edge detection and thinning processing, attains character description of image and character dots of the contour. fourthly, the paper processes the coordinate transformation to character dots and basic splines fitting, imports correlative condition to devise meshing line and meshing track
本文首先介紹了計算機圖形圖像技術的發展與應用情況，對計算機圖形學和數字圖像處理的一些基本理論和方法如圖形變換矩陣、齊次坐標系、圖像采樣和量化、圖像文件格式、模板操作等內容進行了討論：然後對圖像增強處理的目的和方法進行了介紹，對諸如閥值變換、平滑處理、銳化處理等方法的應用場合進行了說明，並對實物圖像的處理結果進行了分析與比較；接下來介紹了數學形態學方法、對增強后的圖像進行邊緣檢測的方法和圖像的特徵描述方法，並獲取輪廓的特徵點：隨后對獲取的特徵點進行坐標變換，並進行b樣條曲線擬合，引入相關條件生成齒輪副的嚙合線及嚙合軌跡：最後引入等值線和區域填充表示方法，並以等值線和區域填充的形式對弧齒錐齒輪嚙合模擬的載荷分佈情況進行了直觀的表示。Special security features have been incorporated into the new definitive stamps. they include the use of a new type of stamp paper with multiple security fibres and an elliptical perforation in the middle of each vertical of the stamp. for high value stamps, iridescent ink is printed in the middle to give a shiny effect when viewing the stamp at different angles
新通用郵票在多方面加強了郵票的防偽特徵，包括印刷郵票選用紙張混有多種纖維，而郵票左右兩邊的垂直中間位置則有橢圓齒孔；高面額郵票的中間部分更以幻彩變色油墨印刷，即使從不同角度觀看，郵票都充滿光澤。This paper discusses the shape optimization problem of 3 - d elastic contact objects in theory using bem, and analyses the real contact problem of bears and rolls
