摘要: 提出了一种基于小波分解的方法来定位车牌。该算法利用数学形态学对边缘图像进行处理,并进行小波分解,只需要进行水平扫描,克服了传统算法中需要水平和垂直扫描的弊端,同时有效地抑制了车辆边缘的干扰信息。

Abstract: This article introduces a method that based on wavelet decomposition to locate license plates. The method is as follow: first process the edge image by using mathematic morphology, and then carry on wavelet decompose on it. This method overcomes the difficulty of both horizontal and vertical scanning in the traditional method as it only needs horizontal scanning. Meanwhile, it has effectively suppressed the disturbing information from vehicle’s edge.

Key words: Image processing, License plate localization, Wavelet decomposition
