詳細討論了在人臉檢測過程中涉及的有關數字圖像處理理論，提出了一種視頻運動圖像中快捷、魯棒的人臉區檢測演算法，並用vc6 . 0開發了一套原型程序「金睛人臉檢測系統」驗證了這一演算法的有效性和檢測精確率，同時實現了數字視頻錄像（ dvr ）的主體功能。The advent of the internet and the wide availability ofcomputers, scanners and printers make digital data acquisition, exchange and transmission a simple task. however, making digital data accessible to others through networks also creates opportunities for malicious parties to make salable copies of copyrighted content without permission of the content owner. digital watermarking is likely to be a potential solution to this problem. digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia documents in networked environments. it makes possible to embed a watermark ( such as identification data, serials number, text or image etc. ) to multimedia documents allowing copyright protection, secret communication, document authentication and so on. in this paper, we present a new digital image watermarking method based on svd ( singular value decomposition ), and then give some theoretical analysis about the algorithm. extensive experimental results show that this method is much more robust than other methods presented before
隨著計算機和網路技術的飛速發展，數字圖像、音頻和視頻產品愈來愈需要一種有效的版權保護方法，另外通信系統在網路環境下的信息安全問題也日益顯露出來.數字圖像水印技術為上述問題提供了一個潛在的解決方案.所謂水印技術就是將數字、序列號、文字、圖像標志等版權信息嵌入到多媒體數據中，以起到版權保護、秘密通信、數據文件的真偽鑒別和產品標志等作用.本文提出了一種新的基於奇異值分解的數字水印演算法並且對該方法的理論基礎給出分析.實驗結果表明這種方法要比目前提出的流行演算法魯棒In this paper, chroma dc coefficients are selected as the carrier data because chroma dc coefficients are robust. also, alterable steps are used to select one part of the coefficients, so the watermark is imperceptible ; before watermark embedding, the watermark is divided into many parts, every part is individually embedded into one gop of the video, even if a gop is destroyed, the watermark can be extracted correctly, this methods promotes the robustness of the watermark ; in addition, in order to promote the security of the watermark, the user ' s id and password are used to generate chaos sequence by the chaos system which is created in this paper, later, watermark is mixed by the chaos sequence. also, the embedding position of the watermark bit is modified by one chaos sequence, so, unauthorized person can not extract or remove the watermark, since the embedding position is unknown
本文認為，色度dc系數是魯棒性非常好的參數，因而選擇色度dc系數作為水印信息載體，同時，採用可變的步長選擇部分系數，保證了水印的隱形性；在嵌入水印時，本文採用水印信息「網格劃分」 、各子塊獨立嵌入視頻的方案，由於水印信息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖組當中，即使某一圖組收到一定破壞，也能夠恢復水印信息，使水印的健壯性得到提高；此外，為了提高水印信息的安全性，在嵌入水印信息時，根據用戶輸入的id號和密碼，利用本文構造的混沌系統產生的混沌序列對水印信息進行變換，同時，對每一水印信息比特的嵌入位置也採用了偽隨機序列進行調整，這樣，未授權用戶不能提取水印信息，也難以擦除其中的水印信息，因為嵌入的位置是未知的。In the tracking of whole body, a model is described according to the body shape. using this model, simple and complicated movements such as walking and throwing motion are labeled, and the 2 - d coordinates of joints can be got. at last, the 3 - d positions of joints are obtained by the model of perspective projection combined with the relationship among joints, and human motion is recovered by 3 - d stick model
在對全身運動跟蹤中，根據人體的形狀特徵描繪了人體區域模型圖，對全身步行及體操動作進行了二維跟蹤和標定，之後再利用攝像機的透視投影模型、人體關節間的骨骼連接關系和比例參數，把關節點在圖像序列中二維坐標恢復為三維坐標，最後用棒狀圖恢復了人體的三維結構。Ll : this reminds me of when i played baseball as a kid. every once in a while a parent would get upset with the umpire and make a big stink
這不僅是你小時候打棒球的情況，現在也是那樣。美國家長特別重視孩子的體育活動，有比賽必到現場，為孩子打氣。覺得不公平還會對裁判大喊大叫。我父母只有在我學習成績不好的時候才會嚴厲批評。Integrated “ baseball bat ” bumpers above and below the window add built - in protection against abusive traffic
視窗上下部的棒狀級沖器與門板完美的融為一體，更可適合現代的裝飾風格。In retrieval algorithm, a row - column coded retrieval algorithm is developed, which is robust to the frame shift and illumination changing. a novel hierarchical architecture to organize different algorithms in content - based retrieval is proposed. experiment shows that this architecture improves the retrieval efficiency
在檢索演算法方面，提出了一種基於行列塊編碼的視頻檢索演算法，該演算法對檢索中視頻移位和亮度的變化具有魯棒性;針對視頻檢索演算法的組織，提出了一種層次化的體系結構，相比傳統的檢索模式，在效果一致的前提下減少了將近40 %的時間開銷。分享友人
