运动目标检测是计算机视觉中重要的课题,运动目标的正确检测与正确分割影响着后续目标的跟踪与识别;光流法是运动目标检测和分析的重要方法,它能够在不知道任何预先场景情况下检测出独立的运动目标,并且可适用于动态场景的情况。首先介绍了光流的基本概念,然后介绍了常用的光流的四种算法;接着以智能交通中路口车辆视频为例,将这四种光流算法用于车辆检测,然后对四种光流算法的优缺点进行分析;最后对光流法在未来可能研究及改进的方向提出展望。
運動目標檢測是計算機視覺中重要的課題,運動目標的正確檢測與正確分割影響著後續目標的跟蹤與識彆;光流法是運動目標檢測和分析的重要方法,它能夠在不知道任何預先場景情況下檢測齣獨立的運動目標,併且可適用于動態場景的情況。首先介紹瞭光流的基本概唸,然後介紹瞭常用的光流的四種算法;接著以智能交通中路口車輛視頻為例,將這四種光流算法用于車輛檢測,然後對四種光流算法的優缺點進行分析;最後對光流法在未來可能研究及改進的方嚮提齣展望。

Moving object detection is currently one of the most active subjects in the domain of computer vision. Moving ob?ject detection and segmentation influence tracking and classification of the follow?up objects. Optical flow algorithm is an impor?tant method for moving object detection and analysis. It can detect the independent moving object in unknown scene and dynam?ic scene. The basic concept of optical flow is introduced in this paper at first and then the four common optical flow algorithms, which are applied to detection of vehicles at the crossroads in intelligent transportation video. The advantages and disadvantages of the four optical flow algorithms are analyzed while possible researches and modified direction prospect of the optical flow algo?rithms are proposed at the end.
