摘要

本工作旨在利用图像处理技术实现巴西车牌定位。在本文中，我们展示了如何根据车牌在整车图像中的频率特征来找到车牌的水平位置。初步结果表明，在良好的照明条件下，图像的效率在96%以上。

Localization of Brazilian vehicles plates using frequency analysis

This work aims at the implementation of Brazilian vehicle plate localization using image processing techniques. In this paper, we show how to find the horizontal position of the plate based on its frequency characteristics in the whole vehicle image. Preliminary results show efficiencies above 96% for images in good illumination conditions.
