Description: 背景差異法(Frame Diference)
此方法是以前景與背景的畫面不同，依據視訊擷取的背景資料 去取得較穩定可信任的資訊，去計算前景與固定背景的像素差異情形，以整合畫素為基礎(pixel-based)與高階區域為基礎(region-based)的資訊，管理 一些視訊並允許其背景資料 的突然改變，這個混合模式嵌入了貝氏機率理 論並允許多個物件的追蹤，有些學者提出以背景差異(background subtraction)模式為基礎去探索移動物件的陰影消除，此方法採用線上初始化(on-line initialization)演算法快速地訓練出正確的背景資訊，他們強調如何有效率並正確的建立背景資訊，以防止判斷錯誤所造成的誤差，這些研究在也同樣強調如何盡快而可靠的找出未覆蓋的背景(uncovered background)資訊。
-Background difference method (Frame Diference) This method is based on foreground and background of different scenes, based on video capture background information to obtain more stable trusted information, to calculate the prospects for fixed-pixel differences in background, in order to integrate painting Su-based (pixel-based) and high-end basic region (region-based) information Platform: |

Description: 使用差影法，将前后两帧图象进行相减，并对相减得到的结果帧进行检测，如果结果帧几乎为空帧，则认为这两帧图象无变化，并把无变化的帧删掉；否则认为这两帧图象有变化，并把它们保存在结果队列中-The use of poor shadow method, the two images before and after the subtraction, and subtracting the results obtained frame detection, the frame if the result is almost empty frames, then the view that no change in the two frame images, and to no change in the frame deleted otherwise, consider that the two frame images have changed, and to save them in the results queue Platform: |

Description: Frame difference is arguably the simplest form of background subtraction. The current frame is simply subtracted from the previous frame, and if the difference in pixel values for a given pixel is greater than a threshold Ts, the pixel is considered part of the foreground. Platform: |

Description: 本文选用了背景减法、帧间差分法和光流法。背景减法是通过将当前帧与背景帧相减得出灰度差值并将此差值与阈值比较判断是否有运动目标。-This paper chose the background subtraction and frame difference method and optical flow method.Background subtraction is through to the current frame and background frame subtraction gray level difference and compare the difference with threshold judgment whether there is a moving target.
