基于复合顺序形态变换的车牌边缘检测

边缘检测是图像分割的重要环节,边缘提取的好坏直接影响了整个图像处理的效果。数学形态学用具有一定形态结构的“结构元素”去度量图像的形态,以解决图像处理和分析问题。文章通过对多种边缘检测方法的分析比较,结合高速公路路口汽车图像噪声大的特点,提出了基于复合顺序形态变换的车牌边缘检测。该方法不但能有效地改善有噪图像边缘检测的效果,鲁棒性好,而且并行快速,便于硬件实现。

License Plate Edge Detection Based on Compound Order Morphology Transform

Edge detection is the important link of image seg-mentation,the quality of edge drawing affect the result of image processing directly.Mathematics morphology uses the structural element that has structure form to detect the morphology of im-age,in order to solve the problem in image processing and analysis.Through comparing and analysis of various edge de-tection method,combining the characteristic of automobile im-age noise big of highway crossing,this paper propose the li-cense plate edge detection based on compound order morpholo-gy transform.This method can not only improve efficiently the effect of the edge detection of image that contains noise,but al-so has good robustness,parallel and fast and the hardware real-ization easily.
