Digital image processing consume a large amount of memory and time commonly. basing on the advantage of fpga, the paper design harware module by hdl ( hardware language ), i. e., some function is achieved by les ( logic element ) of the fpga. the real - time of digital image processing is achieved by this. the sample and display of digital image is the important part. so, the paper mainly design the sample and desplay module. the sample card is designed and it ’ s word mode is configured according china ’ s cvbs ( composite video bar signal ). for acquiring the image and storing it correctly to sram, the paper design the sample - control module. the sample module can work correctly using least time. the reliability and real - time achieve the reference. according the vga principle and scheduling of the ths8134, the paper design a vga - control module by hdl. firstly, the control signal is synthesized secondly, the horirontal and vertical synchronization signals is synthesized according to the vga interface standard
圖像處理的特點是處理的數據量大，處理非常耗時，為實現數字圖像的實時處理，本文研究了在fpga上用硬體描述語言實現功能模塊的方法，通過功能模塊的硬體化，解決了視頻圖像處理的速度問題。圖像數據的正確採集和顯示輸出是其中的兩個重要的模塊，因此，本文主要完成了圖像數據的採集和顯示輸出的設計。本文設計了採集卡，並要對其工作模式進行了配置和編寫了採集控制模塊，在採集控制模塊的控制下，將數字圖像數據正確無誤的存儲到了sram中。 -

However, most of the current wireless networks still work in low bandwidths, and mobile devices still suffer from weak computational power, short battery lifetime and limited display capability. therefore, this thesis deals with developing a very low bit - rate bi - level video coding technique, which can be used in video communications almost anywhere, anytime on any device as follows : ( 1 ) convert true color video sequences from ccd and video card to grayscale ones, ( 2 ) detect static region of successive frames by the sum of absolute differences ( sad ) and update current frame using static region of previous frame, to decrease flicker. ( 3 ) threshold the images to bi - level video sequences using ridler ' s iterative selection
為此，本論文在傳統h . 26x和mpeg - x等視頻編解碼技術的基礎上提出了一種新的基於輪廓的視頻編解碼方案，步驟如下： （ 1 ）先把從ccd攝像頭捕捉到的視頻幀序列轉換成灰度幀序列， （ 2 ）在灰度幀序列的基礎上通過sad演算法找出相鄰幀的靜態區域，用前一幀的靜態區域更新當前幀的相應區域，這樣可以降低畫面閃爍， （ 3 ）然後用灰度直方圖迭代所產生的閾值二值化圖像，生成基於輪廓的視頻幀序列， （ 4 ）最後運用基於上下文的算術編碼技術對由第三步生成的二值化視頻幀序列進行算術編碼。 -
The quantitative measure of parameters mainly includes cytomorphological analysis, immunohistochemical analysis, morphometric measure of vascular network, etc. we utilize self - developed mvpci - v3a card as image capture board. this ipp - based plug - in can accomplish many functions, such as sampling, display, storage, and setting video parameters and access mode
我們採用優秀國產板卡mvpci系列的v3a卡作為圖像捕捉卡，編寫ipp模塊插件完成圖像採集、顯示、存儲、窗口設定、視頻參數設置及圖像文件存取等功能。 -
