  5. The calculation formula of micropiv technique is the original definition of velocity : v = [ s ( t2 ) - s ( tl ) ] / ( t2 - tl ). on the two neighboring frame of images, we search for the two small areas which have the largest correlation. by dividing their distance by their shooting interval, we got the average velocity of this small area in this interval, and then got the velocity of full flow

    Piv測試原理的計算公式，是速度的原始定義： v = [ s （ t _ 2 ） - s （ t _ 1 ） ] （ t _ 2 - t _ 1 ） 。在相鄰兩幀圖像上，找出相關度最大的兩個小區域，用它們之間的距離除以兩次拍攝之間的時間間隔，就得到這個小區域在間隔時間內的平均速度，進而得到整個流場的速度分佈。
  6. A new sequential images sub - splicing method is proposed, which based on features of markers and aimed at looking for the same markers in overlapped area of two adjacent images to finish the splicing task. no real image coalescence is done, but the redundant information is diminished, so the two adjacent images are considered well spliced. big marks are interlaced with small ones to realize accurate image sub - splicing in real situation

    闡述了種子動態圖像拼接原理，提出了動態圖像亞拼接檢測方法，該方法基於標記特徵，以搜尋相鄰兩幀圖像中重疊區域內相同標記為目標，利用相同標記在前後兩幀圖像中應具有相同特徵向量的特點，通過特徵向量的匹配，實現冗餘圖像信息的去除，達到相鄰兩幀圖像的拼；提出了大小間隔的標記方案，以適應採集工況，實現準確圖像亞拼接；研究了重疊區域寬度對拼接精度的影響，給出了重替區域寬度設置方式。
  7. Following are detailed steps of this system : in the segmentation section, we use three successive frames to detect the motion infomation of the pictures, by using blockmatching algorithm in two successive frames twice, we can get two pictures composed of motion blocks of the moving object, then we find out the common motion blocks of the two pictures, experiments prove these blocks approximately compose the moving object. after getting the motion blocks, we calculate the center of these blocks as the center of the moving object, thus we can use the center point as the origin, construct n straight linesjoining the boundry of the image and the center. on each line, we can find out a proper point near the object contour according to some criteria, then we use these n points as the initial points of the snake and let the snake converge on the object contour, thus finish the segmentation of the moving object

    本方案的實現過程為：分割部分：對運動目標的前後三幀進行兩次塊匹配運動檢測，通過找出兩個匹配結果中運動圖像塊的公共部分，獲得組成運動目標的圖像塊；求出運動目標圖像塊的形心作為運動目標的中心，以此中心為端點，向四周發散出角度間隔為的n條射線，射線的另一端終止於圖像的邊緣；在每條射線上按照一定的準則（點的梯度和與目標中心的距離在一定閾值范圍內）找出n個初始輪廓點；以這些初始輪廓點作為主動輪廓模型（ snake ）的初始點，用改進的貪婪演算法使snake收斂到待分割的運動目標輪廓上。
  8. Digital video post - processing ic is designed for consumer video format conversion to attain high quality image, which mainly includes de - interlacing spatial conversions and picture rate conversion
