| 摘 要： | 以条带检测的结果初始化道路轮廓,利用balloon snake方法提取道路轮廓.在初始道路轮廓存在缺失的情况下,balloon snake的膨胀作用可以找回丢失的道路片段,提高道路提取的完整性.基于图像梯度和轮廓曲率调节膨胀系数,降低道路提取效果对膨胀系数的敏感,并加快道路轮廓的扩张,减少迭代次数.通过多幅道路图像的试...

| Abstract: | The road contour is initialized with the output of centerline detection and extracted using balloon snakes.Since the missing road segment can be recovered by the expansion of balloon snake,the integrality of road contour extraction is improved.Compared with the constant expansion coefficient,tuning the expansion coefficient according to image gradient and curvature produce more stable output and the expansion is accelerated.Several road images were used for testing and the results demonstrate its effectiven... |
