This paper illustrates detailedly the thin groupware auto - adaptive recognition system ; it also illlustrates the procession of capture image and take indispensable foreclose to wipe off noise in order to get boundary easilyer. the recognition system uses " hough " transform method to make the recognition area orientation, and according to the unstable environment such as lights which leads to the change of the image ' s brightness, thresholds picture using an iterative selection method and then growing process for cell image segmentation based on local color similarity and global shape criteria, adaptively gets the best threshold to divide the washer off the background. the recognition system uses the classifier based on minimal - error - ratio bayes method to make decision after getting image characteristic
本文詳細介紹了薄形組合件自適應識別系統；闡明了圖像的分通道自動採集過程，以及對採集到的原始圖像所進行的預處理方法。通過採用哈夫變換去除偽邊緣點的方法，有效地解決了識別區域的定位問題。針對裝配零件（主要是墊片）薄、小導致圖像信息少、識別難度大，以及材質不一導致採集到的組合件圖像亮度波動等問題，提出了使用最佳閾值迭代法和使用種子填充的圖像串列分割技術，自適應地找出最佳閡值，使墊片和背景分離，從而提取墊片數目信息。The article first analyses the major vulnerabilities of sip : plain text transmission of sip messages and the lack of effective mechanisms for identification, then do research on the security threats caused by the vulnerabilities of sip, including registration hijacking, impersonating a server, tampering with message bodies, tearing down sessions and denial of service. after setting up a sip communication platform in the laboratory environment, the article confirms the existence of security risks by using simulation attacking experiments
本文首先分析sip協議主要的脆弱性: sip消息明文傳送和缺乏有力的身份鑒定機制，以及由於這些脆弱性而引發的包括注冊劫持、服務器偽裝、消息篡改、拆卸會話和拒絕服務等的安全威脅，並通過在實驗室環境下搭建的sip通信平臺，進行模擬攻擊實驗來證實問題的存在性。Digital products copyright protection, information content security and security communication make information hiding that is a new science and art of information security field. as an effective technique used for convert communication and copyright protection, information hiding has drawn a lot of attention over the past few years in the field of information security
