论文摘要
自然场景中的道路标志检测和认可是智能运输系统（ITS）设计中最重要的任务之一。但是，照明变化仍然是一个主要问题。在本文中，提出了基于光度不变剂的有效路标分割的有效分析。该方法是基于使用混合距离的颜色内形式，通过利用chro-matic距离和红色和蓝色比率，在l theta phi颜色空间上，它是不变，阴影和阴影变化的不变的。进行了比较研究，以证明这种方法对道路标志分割的最常用方法的鲁棒性。实验结果和详细的分析表明，本文描述的算法的高性能。
Road signs detection and recognition in natural scenes is one of the most important tasksin the design of Intelligent Transport Systems (ITS). However, illumination changes remain a major problem. In this paper, an efficient ap-proach of road signs segmentation based on photometric invariants is proposed. This method is based on color in-formation using a hybrid distance, by exploiting the chro-matic distance and the red and blue ratio, on l Theta Phi color space which is invariant to highlight, shading and shadow changes. A comparative study is performed to demonstrate the robustness of this approach over the most frequently used methods for road sign segmentation. The experimental results and the detailed analysis show the high performance of the algorithm described in this paper.
