    • A method and apparatus for detecting vehicle headlights and a region-of-interest (ROI) segmenting method and apparatus are disclosed. The ROI segmenting method includes: performing an edge extracting operation on a captured image to obtain edges of the captured image; selecting edges meeting predetermined criteria from the obtained edges, the predetermined criteria being the similarity between the region surrounded by the selected edges and the pattern formed by a vehicle headlight in physical reality at a position of the selected edges; determining the region surrounded by the selected edges within the captured image as a vehicle headlight pattern; and segmenting the ROI which potentially includes the vehicle pattern from the captured image based on the determined vehicle headlight pattern. With such a method and apparatus, the ROI of a vehicle may be acquired from the image without using the vehicle's bottom shadow.
    • 公开了一种用于检测车辆前灯和感兴趣区域(ROI)分割方法和装置的方法和装置。 ROI分割方法包括:对拍摄图像执行边缘提取操作以获得拍摄图像的边缘; 从所获得的边缘选择满足预定标准的边缘,所述预定标准是在所选边缘的位置处的物理现实中由所选边缘包围的区域与由车辆前灯形成的图案之间的相似度; 确定由拍摄图像内的所选边缘包围的区域作为车辆头灯图案; 以及基于所确定的车辆头灯图案,从捕获的图像分割潜在地包括车辆图案的ROI。 利用这种方法和装置,可以从图像中获取车辆的ROI,而不使用车辆的底部阴影。
