Gait Recognition Software Proposed For Surveillance At A Distance步態識別軟件的建議進行監視，在距 Tuesday, June 10th, 2008 週二， 2008年6月10日
C. Nandini of the Vidya Vikas Institute of Engineering & Technology and CN Ravi Kumar of the SJ College of Engineering in Mysore, India, explain that human gait typifies the motion characteristics of an individual.長nandini的vidya vikas研究所的工程技術和CN拉維庫馬爾的律政司司長工程學院在邁索爾，印度，解釋說，人類的步態典型的運動特性， 1個人。 Viewed from the side, we each have a unique gait that makes us easily recognizable.從方面，我們都有一個獨特的步態，令我們很容易辨識。 They point out that a camera with a side view can record a set of key frames, or stances, as a person heads for the security desk at an airport, military installation or bank, for instance.他們指出，相機與側視圖可以錄製了一套關鍵幀，或立場，作為一個人元首為安全台在機場，軍事設施或銀行，例如。 Key frames over the person’s complete walk cycle, can then be converted into silhouette form and statistical analysis using so-called Shannon entropy, together with height measurements and the periodicity of the gait used to classify the person’s gait.關鍵幀以上的人的完整的步行週期，便可以轉化為剪影的形式和統計分析，利用所謂的Shannon熵，加上高度的測量和週期步態用來區分人的步態。 The gait of individuals checking in at an airport could then be compared with the database, perhaps even before they enter the airport concourse.步態檢查個人在一個機場便可以與數據庫，甚至之前，他們進入機場大堂。 Such data compared with CCTV footage might also be used to track suspect terrorists or criminals who may otherwise be disguising their features or be carrying forged documents.這些數據相比，與中央電視台的畫面也可能被用於跟踪懷疑恐怖分子或罪犯，誰可能，否則掩飾其功能或進行偽造證件。 The researchers emphasize that gait recognition has a significant advantage over more well-known biometrics, such as fingerprinting and iris scanning in that it is entirely unobtrusive and can be used to identify an individual potentially from a considerable distance.研究人員強調，步態識別有一個顯著的優勢，更著名的生物識別技術，如指紋識別和虹膜掃描，因為它是完全不突兀，可以用來識別個人可能從一個相當大的距離。 “The ability to identify a possible threat from a distance gives personnel a longer time frame in which to react before a possible suspect becomes a real threat,” the researchers say. “識別能力可能的威脅，從遠處人員給予較長的時間框架，在作出反應之前，可能嫌疑人成為了真正的威脅， ”研究人員說。 They carried out initial tests on 20 people recorded walk in a straight line at normal speed and stride, back and forth in front of a video camera placed perpendicular to their path.他們進行的初步測試， 20人，錄得走在一條直線，在正常的速度和跨越，背部及提出的在前面的一部攝錄機放在垂直的道路。 They obtained good recognition rates using the Shannon entropy equation and the individuals’ height.他們取得了良好的識別率使用Shannon熵方程和個人的高度。 Recognition performance of the system was sensitive to changes in big viewing angle above ten degrees but was reasonably robust even when the individuals changed walking speed.識別系統的性能敏感的變化，大視角10度以上的，但合理的強勁，甚至當個人改變了步行速度。 “Comprehensive framework to gait recognition,” by C. Nandini and CN Ravi Kumar in International Journal of Biometrics, 2008, 1(1), 129-137 “綜合框架，以步態識別” ，由長nandini和CN拉維庫馬爾在國際期刊的生物識別技術，到2008年， 1 （ 1 ） ， 129-137 See More: 看到更多的： Big Brother 大哥哥 Technology 技術 USA News 美國新聞Have Your Say: Gait Recognition Software Proposed For Surveillance At A Distance 你說：步態識別軟件的建議進行監視，在距 Please note, only selected comments will be published.請注意，只有選定的評論將出版。 Or discuss this report in our new forums 或討論這個報告在我們的新論壇 One Response to “Gait Recognition Software Proposed For Surveillance At A Distance” 1回應“步態識別軟件的建議進行監視在距離”

This is pretty interesting technology, and it could eventually filter down to a product that can be installed on future surveillance systems to enhance the other features like facial recognition and specific area monitoring.這是相當有趣的技術，以及它可能最終篩選到一個產品，可以安裝於未來的監視系統，以提高其他功能，如面部識別和特定地區的監測。 As long as it’s used for law enforcement purposes.只要它的用於執法目的。 Great story and keep them coming.偉大的故事，讓他們來。
