| 摘 要： | 针对减背景算法中复杂背景下背景帧的提取问题，给出了一种码本背景提取方法。利用视频图像序列中的颜色和亮度信息，为每一个像素点创建一个码本，且码本随着其中码字的更新而更新，所有像素点的码本构成一个完整的背景。用当前视频帧和码本进行比较得到前景运动目标。结果表明：算法运算量小，适合做实时处理。

| Abstract: | Aimed at the problem that how to attain background frame during background subtraction in complex condition,a codebook background method is presented.It uses the information of color and brightness from video image to create a codebook for every pixel.And the codebook of every pixel updates with the update of code word.So the codebooks of all pixels construct the whole background.The comparison between the pixel values of current frames and the codebooks is done to detect foreground pixels.This algorithm is efficient in computation and is suitable for real-time processing. |
