  1. At the receiving end, a inverse process is performed. the system receives low rate data and the fpga reorganizes a frame of data which is decoded by the compression chip every 20 ms. the obtained pcm signal is performed d / a to restore the analog speech signal

    端進行相反的過程,接率數據,並由fpga重新幀,送至主晶元解pcm,再作d / a變換,恢復出模擬語音,系統是全雙工的。
  2. Restructure the code so the thread exits gracefully when a signal is received

    重新織代結構,以便接時線程能夠正常退出。
  3. Vecon - con system is triggered by 4 infra - red sensors along the selected lanes with 2 in pairs. false trigger by wind shield and container - type trucks are dalian yaowan phase ii screened out and the system captures and recognizes container numbers, country codes, iso codes automatically in less than 0. 012 seconds from trigger till image capture. the captured images are transmitted to the tos for processing which enhances efficiency and ensures security while maintaining manpower at the minimal

    Vecon - con透過四個紅外線對射敏應觸發器進行觸發,兩個一並列于車道上,具備防止集裝箱型卡車大型集裝箱車拖頭等誤觸發,系統接觸發后,自動抓拍集裝箱國家代箱形代,抓拍的圖像會被傳送頭控制系統中心進行后臺處理,該系統由觸發抓拍只需不多於0 . 012秒,整個系統大大提高了口岸工作效率,並減低了人力物力的耗用,為港口頭的管理提供了更加高效可靠的處理手段。
  4. 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,本文採用水印息「網格劃分」 、各子塊獨立嵌入視頻的方案,由於水印息子塊是相對獨立的嵌入視頻中的每一相對獨立的圖當中,即使某一圖一定破壞,也能夠恢復水印息,使水印的健壯性得提高;此外,為了提高水印息的安全性,在嵌入水印息時,根據用戶輸入的id和密,利用本文構造的混沌系統產生的混沌序列對水印息進行變換,同時,對每一水印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息,也難以擦除其中的水印息,因為嵌入的位置是未知的。
