| 摘 要： | 针对车牌识别中所拍摄的图像序列存在分辨率较低的问题，提出了利用图像间的互补信息来重建一幅高分辨率图像的方法，以便于车牌图像的识别。通过迭代求解法和高斯金字塔模型，快速精确地估计得到配准参数，采用凸集投影（POCS）算法对图像序列进行了超分辨率重建。实验表明算法具有亚像素级的配准精度和较强的稳健性，重建图像取得了良好的视觉效果。

| Abstract: | In respect to a sequence of low resolution images used in license plate recognition,a method proposed which use the image complementary information to reconstruction a high-resolution image in order to facilitate the identification of license plate images.In this paper,after the estimated registration parameters quickly and precisely acquired with gauss pyramid model and iterative solving process,the super-resolution reconstruction of the image sequence can be realized with projection onto convex sets(POCS)... |
