  1. Structure to the right of the subtraction operator

    減法運算符右側的源
  2. The subtract operator, however, is not commutative ; therefore, you need two operations to handle the value to be subtracted and the value from which the subtraction will take place

    但是,減法運算符是不可交換的;所以,需要兩個操作來處理減數和被減數。清單3為這個目的定義了閉包
  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。
  4. In addition to standard addition, subtraction, multiplication, and division, awk allows us to use the previously demonstrated exponent operator " ", the modulo remainder operator " % ", and a bunch of other handy assignment operators borrowed from c

    除了標準的加、減、乘、除, awk還允許使用前面演示過的指數運算符" ^ " 、模(余數)運算符" % "和其它許多從c語言中借入的易於使用的賦值操作符。
  5. The - ( subtraction ) operator yields the difference of its arguments. the numeric arguments are first converted to a common type

    減)計算參數的差,數值型的參數首先轉換成通用類型
  6. Structure to the left of the subtraction operator

    減法運算符左側的源
  7. The subtraction operator subtracts the second

    該減法運算符從第一個
  8. On the right side of the subtraction operator

    減法運算符右側的
  9. On the left side of the subtraction operator

    減法運算符左側的
  10. The subtraction operator the second

    該減法運算符從第一個
  11. Operator is the binary arithmetic subtraction operator for the difference between two numeric expressions

    運算符為二進制演算法減法運算符,用於計算兩個數值表達式之差。
  12. Thus, in the following example, multiplication is performed before subtraction even though the subtraction operator appears before the multiplication operator in the expression

    因此,在下面的示例中,雖然表達式中減法運算符出現在乘法運算符之前,但是先計算相乘。
  13. When the subtraction assignment operator

    如果使用減法賦值運算符(
