| 摘 要： | 利用阴影区域内的点与背景对应点颜色的比值大小，以及该点和汽车的空间位置关系以及汽车的形状有关的特征，提出一种新的基于空间特征的汽车阴影分割方法，该方法不仅适用于汽车与阴影颜色差别明显时的汽车阴影分割，在当两者颜色相近时，也能获得较好的分割效果。实验结果显示了该方法的有效性。

| Abstract: | With the color ratio size between the point within the shadow area and the corresponding point in background, the relationship between the point and vehicle spatial position, and the vehicle shape a new vehicle shadow segmentation method based on its spatial characteristics is proposed. The method is not only suitable for vehicle shadow segmentation when the color difference between vehicle and shadow is obvious, the better segmentation effects can be also obtained even if their color is similar. The experimental results show the effectiveness of method. |
