摘要: | 在自动化的车辆监视系统中,颜色辨识是一项重要的议题。车辆的颜色是一项重要的特征,它可以帮助我们去辨识这辆车子的身分。在这篇论文中,我们提出一个以降低反光影响的方法去分类车辆的颜色。首先,使用影像切割演算法把影像切成几个区域,找出最有可能是车辆外壳的那个区域。由于受到车壳上反光的影响,会使得影像切割后车壳会变成几块破碎的区域,我们将很难找到完整的车辆外壳的区域。因此,我们使用了一个去反光的方法分开反光的成分和漫射的成分,以降低反光所造成的影响。最后,我们找出车辆车壳的区域,计算它的主要颜色以分类车辆的颜色。我们从几个不同的网站上下载七种不同颜色的车辆图片当作实验的资料,实验的结果显示出我们提出的方法有令人满意的结果。 Color recognition is an important issue in automatic vehicle surveillance. The vehicle color is a critical feature to help identify cars. In this thesis, we propose a novel approach for vehicle color classification. Firstly, we use image segmentation algorithm to divide image into regions and extract the vehicle shell part from them. Since the light reflection will influence, the broken regions on car shell after image segmentation, we can’t find a complete car shell well in images. Thus, we use the specular-to-diffuse mechanism to separate specular component and diffuse component and reduce the light reflection influence. Finally, we extract the vehicle shell region and calculate the dominant color of the shell region to classify the vehicle color. We download the 7 kinds of different color vehicle images from Internet web sites. The experimental results demonstrate good performance and thus show the effectiveness of the proposed schemes. |
