中文摘要：

通过对视频交通场景特点的分析，提出了基于视频技术的交通场景背景生成及其更新方法——背景相异像素迭代法。并通过试验和与其他算法进行比较，证明了该算法背景生成和更新的可行性和先进性，解决了在交通流密度比较大的情况下难以进行背景生成和更新的问题。本算法对于提高交通视频检测在实际应用中的准确性和适用性具有重要的意义。

英文摘要：

According to the character of traffic video scene, a new method called different background pixel iteration algorithm was proposed for background generation and updating of traffic scene based on video technology. Experimental results and the comparison with other method prove that the proposed method is feasible and Mvanced for generating and updating background under the condition of high traffic flow density. It is meaningful to employ this method to improve the accuracy and applicability of application in traffic video detection.
