  1. It employs a series of processing methods. for example, it employs different method of threshold according to illumination and the characteristic of the dial plate ; employs the method of mathematic form filtering according to the thought of the line is the most important in image ; employs the method of beeline matching according to the characteristic of the line

    此系統利用了圖像處理的基本思想，採用了一系列的處理方法，如根據照度及表盤特點採用了不同的二值化方法；根據圖像中線條最重要的思想對圖像的濾波採用了數學形態濾波方法；根據線條特點提出了利用直線擬合的方法等。
  2. At the meantime, during the procedure of pre - processing, according to the character that the illumination conditions on the scene of the expressway toll collection frequently change a lot, the algorithm of first difference combining the method of fixing the threshold of binarization via accumulating the points was used to complete the job of extracting the outline of the image

    在圖像預處理過程中，根據高速公路收費站點光照條件不斷變化的特點，採用一階差分演算法並結合累積像素點確定二值化閾值的方法，完成圖像邊緣輪廓的提取工作。
  3. A statistical method is used to obtain the background model, which is updated real time in order to adapt to illumination changes and scene changes. after threshold operation, morphologic operation and connected region area measurement are introduced to solve background disturb problem. at last, shadows are detected using hsv color space information and gets exact moving regions

    該方法首先利用統計的方法得到背景模型，並實時地對背景模型進行更新，以適應外界光線變化和場景本身的變化，閾值操作后，用形態學和連通域檢測的方法進行后處理，消除噪聲和背景擾動帶來的影響，最後，在hsv顏色空間下檢測出陰影，得到準確的運動對象區域。
  4. The images to be processed is obtained in condition of nonuniform illumination. a threshold surface by interpolating zero - crossing points is used to segment image to avoid influence of nonuniform illumination. then the destination region can be detected using the method of pattern recognition and the method advoid the influence of nonuniform illumination effectively. the contour description is obtained by fitting at least squares principle

    論文在分析當前圖象分割的現狀和趨勢的基礎上，採用基於log運算元的動態閾值選取對圖象進行分割，以克服非均勻光場給圖象分割帶來的影響，然後通過對區域特徵的提取和分類準則的確定，準確識別出目標區域。
  5. The algorithm is built on the base of color image sub - way segmentation method. according to the hue and saturation, it can segment color image based on a histogram - based bi - threshold iterative. meanwhile, it captures some feature points to measure illumination variant, real - time update segmentation threshold

    本演算法採用彩色圖像的分通道分割原理，以色度和色調為特徵量進行基於直方圖的雙閾值自動迭代分割，同時利用背景特徵點監測環境光照變化，自適應更新分割閾值。
  6. When processing the shadow of foreground moving objects, in order to overcome the influence of illumination change of part or integrity in the image, the color model of brightness distortion and chrominance distortion is established to distinguish shaded background, highlight background, original background and foreground objects, and then select the threshold automatically to classify the pixel points in the image

    在處理前景目標的陰影問題時，為了克服了圖像局部或整體的光照變化的影響，通過建立亮度變化和色度變化的彩色模型，來區分陰影背景、高亮背景、普通背景及前景目標，然後自動選擇閾值對圖像的像素點進行分類。
