The third, after theoretically analyzing, the following practicable methods are put forward : 1 ) automatically pick - up the synchronous information by analyzing the spectrum of intercepted video - leaking information ; 2 ) realizing the phase lock and the electronic image stabilization by integral - projection and differential - positioning ; 3 ) improving the effect of accumulation mean filter and the pectination filter by using electronic image stabilization ; 4 ) automatically adjusting image acquisition parameters by detecting the image entropy, therefore the quality acquired image is improved ; 5 ) to realize the quantitative test of a leaking extent, a standard test picture was designed. finally, a proto type for leaking information processing based on our techniques mentioned above and the virtual instrument principle was designed and tested
在理論分析的基礎上，提出了以下的實用技術： 1 ）用譜分析方法從截獲的信息中自動提取同步信息； 2 ）用積分投影、微分定位的方法進行相位檢測，實現可靠的鎖相和電子穩像； 3 ）將電子穩像技術用於重加濾波和梳狀濾波的濾波方法，改進了濾波效果； 4 ）通過檢測圖像信息熵實現圖像採集參數的自動調整，改進了圖像採集的質量； 5 ）設計了用於儀器定標的標準測試圖，可以對泄漏信息進行定量檢測。 -
