This kind of validation can only be done by developing a part of the solution " walking skeleton ", " spanning application ", or " tracer bullet " to demonstrate that the architecture is viable
這種確認只能通過開發部分解決方案（ 「骨架」 、 「衍生應用程序」和「曳光彈」 ）來演示體系結構是可行的。 -
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。 -
The experiment materials include two parts, one is the gait database downloaded from casia and the other are several videos we shoot ourselves. we achieve on automatic detection and tracking of leg of walking people, using the arithmetic proposed in this paper. the experiment results indicate that the precision of the tracking of leg skeleton is satisfying, using our algorithm. it gets rid of the restriction of mannual intervention, and also the problem of self - occlusion could be solved effectively
論文以中國科學院自動化研究所下載的步態圖像序列庫及實驗小組自己拍攝的視頻為實驗素材，用本文提出的演算法實現了對步行人體腿部骨架的自動檢測及跟蹤。實驗結果表明，本文演算法對骨架的提取及跟蹤準確度較高，不僅擺脫了手工標注的約束，還有效解決了雙腿自遮擋造成跟蹤準確度降低的問題。 -
Soon they were chatting together, with intervals of listening ; and not long after, hearing no further sound, they shouldered the tools and set forth again, merry walking first with silver s compass to keep them on the right line with skeleton island
偶爾停下來，聽聽，又過了一會兒，聽聽沒再有什麼動靜，就扛起工具又出發了。墨利帶著西爾弗的羅盤走在前頭，以保證他們的方向始終與骷髏島成一條直線。
