The procedure functions in the compare between partial image of dynamic collection and corresponding image of the airscape. in chapter 5, basing on the analysis of correlative theory of digital image, we introduce the improved fasted - down algorithm and simulative anneal algorithm, which applies to nn calculation, an d bring forward the unique and effective means, correlative original value evaluation. basing on the combination of correlative arithmetic, a stable, high - speed and exact correlative arithmetic is formed, which makes it possible to apply computer vision detection of single - needle quilting in industrial production
本文展開研究並取得一定成效:構建了基於pci總線的微機實時圖像
採集系統;在
採集的布料總圖(鳥瞰圖)的基礎上,通過數字圖像的數字濾波、圖像增強、邊緣檢測等處理,提取布料圖像的邊緣,對輪廓的矢量化的象素點進行搜索,得到相應的圖案矢量圖,從而確定絎縫的加工軌跡,生成加工指令;在進給加工過程中,主計算機對動態局部圖像與總圖(鳥瞰圖)的對應部分進行圖像相關的匹配計算,應用數字圖像理論,結合神經網路計算的改進最速下降法和模擬退火演算法,提出獨特而有效的相關迭代初始值賦值方法,形成穩定、高速和準確的相關運算,實現單針絎縫視覺測量和自動控制。

Under mixed culturing conditions, it was observed that bacterial number rapidly incre ; ised soon after the lysing of host cells. on the contrary, while the non - host cyanobacterium ( i. e. anabaena flos - aquae ) was incubated in the mix culturing system, the breeding of the bacteria could be inhibited. it may be suggested from the result above that cyanophage could bring about the changes in microorganism populations
調查結果顯示, 19個
採集的水樣中有6個含有裂解織線藻的噬藻體,而且水樣未經濃縮即能裂解宿主,說明噬藻體在淡水中分佈較廣泛,裂解性也較強;混合培養條件下的研究結果表明,噬藻體裂解宿主后,細菌數量快速增加,而當培養系統中有非宿主藻類存在時,細菌的增殖則受到非宿主藻的抑制,說明噬藻體可以顯著改變系統中微生物的種群結構。
In designing analogic circuit, we adopt programmable filter max262 to meet the system ' s command. after the step, we can make the signal ' s frequency width is wider and noise level is lower. to make the signal ' s amplitude to meet the analogic to digital device ' s command, we adopt the max551 to finish the gain control
在模擬電路部分,
採用可編程濾波器max262 ,這樣就滿足了該數據
