基于帧间差分法的彩色视频背景提取的程序

摘 要

在智能交通系统（ITS）中，提取车辆状况的运行信息，运动目标的提取能够正确、实时地记录道路上车辆行驶情况，从而可以极大地提高排障效率，使道路迅速畅通。所以车辆的实时、有效检测在智能交通系统中很重要。帧间差分法是实现视频检测的方法之一，该方法采用基于像素级和帧级的多级自适应背景更新策略，能够克服光线缓慢变化和剧烈变化对背景的影响，并及时消除由于物体移入和移除产生的鬼影。实验结果表明，利用帧间差分法提取的背景清晰可见。基本上能满足任务要求。

在本文中，本人做了如下工作：查阅相关资料，了解论文所要求的工作，向指导老师请教，然后自己组织论文的整个框架，从编程到截图等整个工作，完成论文的要求。 关键词：运动目标；帧间差分；背景提取；图形滤波；图像二值化

ABSTRACT

In the Intelligent Transportation Systems (ITS), the extraction of vehicle condition the running information of, moving target's extraction of able to correctly, real-time ground recording road vehicles being driven on situation, thus you can greatly improve platoon obstacle efficiency, so that roads rapidly unimpeded. Therefore, real-time vehicle, effective detection in intelligent transportation system is very important. Inter-frame difference method is one of the ways to achieve video detection, the method based on the pixel level and frame-level multi-stage adaptive background updating strategy to overcome the slow changes and dramatic changes in the light affects the background, and promptly eliminate the objects into and removing ghosting. Experimental results show that using inter-frame difference method to extract the background clearly visible. Can basically meet the mission requirements.

In this article, I made the following tasks: access to relevant information, understand the paper work required to ask the instructor, and then organize themselves entire framework papers, etc. from programming to capture the entire work to complete the thesis requirement.

Keywords: Moving target; interframe difference; background extraction, graphics filtering, binarization.
