| 摘 要： | 在许多应用中,自动从图像中探测文字起着非常大的作用。但文字出现在复杂的背景中时,现在的文字分割识别技术却处理的效果很差,车牌识别是从复杂的背景中识别文字的一个典型事例。如何从图像中把车牌自动分割出来,是车牌自动识别的关键一步,该文从车牌字符本身的特征出发,提出了综合运用各种图像处理方法(例如形态学方法等),在图像中定位车牌,并提出了进行矫正的方法。实验表明该方法快速准确,对于清晰度不高的图像也能取得良好的效果。

| Abstract: | Automatic detection and recognition of text embedded in images plays an important role in many applications.But text often appears in textured backgrounds.Current technologies meet many difficulties while doing with these.License-Plate-recognition is a typical example.How to segment the Vehicle-License-Plate from images is a key step before the recognition.In this paper,an algorithm is presented based on the feature of the license plates.It proposes a method of locating and adjusting license plates in images,integrating various image processing methods(morphological methods etc.).Experiments prove that our algorithm is fast and accurate;it is also effective to blur images. |
