Description: There are many approaches for motion detection in continuous video streams. All of them are based on comparison of current video frame with one from the previous frames or with something that we ll call background. In this article I ll try to describe some of the most common approaches. In describing the algorithms, I ll use an image processing library I ve described in my previous article. So, if you are common with it, it will only help. The demo applications support the following types of video sources: AVI files (using Video for Windows, interop library is included) updating JPEG from internet cameras MJPEG (motion JPEG) streams from different internet cameras MMS Stream - Microsoft Media Services local capture device (USB cameras or other capture devices).-There are many approaches for motion detection in continuous video streams.

Description: For many embedded systems USB seems to be a good solution for data acquisition
modules - as USB supports a frame rate of 1 ms which is fast enough for many
feedback control applications. The problem now is that USB is currently only
supported by Windows 98 and updates of Windows 95. The design of the USB host
controller again emphasizes the possibilities using USB in an embedded System:
Once the USB communication is established, the host controller can work in the
background using DMA-memory transfers - accompanied with a synchronous
interrupt every millisecond, a real time feedback control system is easily
established.-For many embedded systems USB seems to be a good solution for data acquisitionmodules- as USB supports a frame rate of 1 ms which is fast enough for manyfeedback control applications.

Description: 使用opencv，将一个视频文件分割成多张图片。
特点：按帧提取，每帧保存为多张图片。
保存时，原来的格式是全彩的，同时转化并保存全彩图片对应的黑白图片和二值化图片。这三类图片分别存放在默认目录的video background foreground中。默认的视频文件名为默认目录下的ci.avi-Using opencv, a video file will be split into multiple images. Features: by frame extraction, each frame is saved as multiple pictures. Preserved when the original format is full color, at the same time transforming and save full-color picture black and white pictures and the corresponding binary image. These three types of images were stored in the default directory in the video background foreground. The default video file name is the default directory ci.avi Platform: |

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: 在显示前台缓存内容中的一帧画面时，后台缓存正在绘制下一帧画面，当绘制完毕，则后台缓存内容便在屏幕上显示出来，而前台正好相反，又在绘制下一帧画面内容。这样循环反复，屏幕上显示的总是已经画好的图形，于是看起来所有的画面都是连续的。
-Cache contents are displayed in front of a screen, the background frame buffer is being drawn the next screen, when the rendering has finished, the cache contents of the background will be displayed on the screen, while the opposite front, but also in drawing the next frame screen content. This cycle repeated, the screen always has been drawn graphics, the screen looks all are continuous. Platform: |
