匿名消息源的使用容易造成不实新闻与虚假报道的泛滥,但在特殊情况下媒体又不得不采取匿名方式处理,以保证爆料人的安全与信源的持续性,匿名消息源的使用“张力”成为各方考量的重要平衡点。以美国《纽约时报》为例,本文对其匿名消息源的使用规范历程进行梳理,重点分析“公共编辑”与“西格委员会”两大约束制度对匿名消息源的规范作用,希望能为我国匿名消息源的使用规范做出参考。

About 60%-70% of traffic accidents are caused by vehicle collisions. And lane change as the most common behavior when driving a vehicle is also the main reason for vehicle collisions. This paper based on the theories of video image processing technology, proposes a driving vehicle lane change recognition algorithm. This paper collects images through binocular CCD camera, adopts the improved method of HOUGH to extract and fit the lane line and divides the images into several security level areas. After using interest function to extract the ROI of the target vehicle, combines with vertical symmetry properties of the vehicle to further determines vehicle position. Then locate the center of the vehicles and use the binocular ranging method to get the distance between the vehicle and the lane lines. Finally, calculate the dispersion of the distance and set appropriate thresholds and determine whether the vehicle have the lane change behavior.
