【摘要】 首先用图像的相位一致性特点对车牌图像进行特征提取;然后对二值图像做投影,并对投影信号做小波变换降低噪声的干扰;最后通过双边缘分割将车牌的垂直和水平边缘检测出来完成车牌的最终定位。实验表明,该算法对不同光照具有一定的鲁棒性,同时具有较好的运行效率。更多还原

【Abstract】 The feathers of license plates are extracted with image phase congruency characteristics,and the projected binary images are dealt with wavelet transformation to reduce the noises.Then both the vertical and horizontal edges of plates are detected by means of double-edge section to locate the plates.Simulation result shows that the algorithm is with robustness and high efficiency.更多还原
