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。 -
To process an iris image, this system needs only 0. 2 second. the eer ( equal error rate ) is 3. 9 % in testing the casia iris library
其中，本系統對一枚虹膜進行處理的速度小於0 . 2秒，在casia虹膜數據庫上測試的eer （等錯誤概率）為3 . 9 % 。 -
We test these algorithms by the casia 2. 0 iris database. this method is proven by the experiment results
這些演算法通過casia2 . 0虹膜庫驗證，實驗結果表明，本論文的方法在實際應用中有較好的性能。 -
The algorithm has made certain improvement and innovation in each stage of the iris recognition. the identification experiments are done in the casia iris database ( version 1. 0 ), and good recognition results are achieved
該演算法在前人研究的基礎上，對虹膜識別的三個階段（虹膜圖像預處理、虹膜特徵提取、匹配識別）都做了一定的改進和創新。 -
Different weighting coefficients are used to multiply the matching result of each part. good recognition results are achieved after 40000 recognition experiments have been done in the casia iris database ( version 1. 0 )
論文的最後對本文的虹膜識別演算法在casia虹膜數據庫（ version1 . 0 ）中進行了40000次的虹膜識別實驗，並得出了較好的識別效果。 -
The proposed approach is compared with two commonly used ones by experimental results on the casia database and is proved its rapidity and precision. ( 2 ) in the image proprocessing, the located iris is transformed from an annual area to a rectangular area, then the image is enhanced and converted to some 1d signals which will facilitate the following work
2 .對定位后的虹膜，採取了有效的歸一化方式，首先在極坐標下把虹膜從環行展成矩形，並對矩形圖像增強，再把矩形圖像化為多個一維信號，這樣，就將二維信號處理問題轉化成了較簡單的一維問題。
