【摘要】 车牌分割是汽车牌照自动识别的基础。本文针对含有车牌的灰度图像,利用车牌字符具有明显垂直纹理的特征,提出了一种适合字符纹理特征的边缘检测方法,获取垂直边缘图。根据车牌固有的特征,运用改进的投影算法确定车牌区域。文中详细给出了车牌分割步骤。实验结果表明,在复杂的背景下,该方法能够快速有效地实现车牌自动分割。更多还原

【Abstract】 The vehicle license plate segmentation is the basic step of the automatic recognition to the vehicle license plates. Observed that in the gray images the characters of vehicle license plates have the obvious vertical texture, a vertical edge detection method was proposed according to the character texture. In the obtained vertical edgy map, an improved projective algorithm based on the inherent feature of the vehicle license plates was used to locate the plate area. The vehicle license plate segmentation algorithm is given in details. The application examples have shown the good segmentation results in the complicated background.更多还原
