  1. Firstly, given the seed point of the interesting region, it detects the edge points that has the shortest distance to seed point in some directions, takes these points as the control points to form the initial b - spline active contour

    該方法是一種圖像兩步分割方法，給出位於感興趣區域內的種子點后，首先用canny運算元檢測出各個方向上與種子點最近的棱邊點，以這些點為控制點，形成初始的b樣條活動圍道。
  2. Among them, the improved initiative profile mode draw - out algorithm not only can precisely drawing out in the image the convexity object edge ; but also can approach the hollow place of the edge 。 at the same time, it introduced the auto - adapted changing size exterior restraint energy to increase the attraction scope, enables the control point not to

    其中，改進主動輪廓模型的邊緣提取演算法不但能精確地提取圖像中的凸形物體的邊緣，而且能夠接近邊緣的凹陷處;同時，它引入了自適應改變大小的外部約束能量來增大吸引范圍，使控制點能夠不依賴于初始輪廓而快速地收斂到目標的真實輪廓。
  3. To this problem a series of image rectification procedure which utilize geometric rectification theory in vehicle license recognition system are pointed out : we first locate vehicle license and execute the edge detection and binary conversion, then proceed calibration in which we use two calibration scheme looking for control point coordinate, one based on the hough transformation, the other based on image analysis method, and finally realize image correction in geometrical transform and bilinear gray interpolation method

    針對此問題本文給出了一套將幾何畸變校正技術應用到汽車牌照自動識別系統中的車牌圖像校正方法：首先提取牌照信息，並對圖像進行邊緣檢測和二值化的預處理；然後提出了基於hough變換控制點提取和基於圖像分析法的控制點提取的兩種實時標定方法；最後通過空間坐標變換和灰度插值完成圖像的校正。
  4. The approach to exactly calculate geometric parameters of subdivision surface, such as limiting point, tangent vector and normal vector, are illustrated. ( 2 ) the number of geometric elements ( vertex, edge, facet ) within control mesh grows exponentially as the increase of subdivision levels in general subdivision schemes

    （ 2 ）在正常的曲面細分過程中，控制網格上幾何元素（頂點、邊、面）的數量是按照幾何級數增加的，會產生龐大的冗餘數據。
  5. The method we designed first selects local area with typical object and extracts edge information from these object, then feature points is matched using a criterion combined with edge shape and gray - level information. in such steps, we obtain robust and steady control point using for image registration

    本文描述的方法通過選取圖像中的典型區域，利用地物特點提取邊緣特徵，並利用邊緣形狀信息和局部灰度統計信息結合作為特徵點提取及同名點匹配的判別準則，可得到符合地物性質及直觀認識的匹配特徵點。
