摘要
在印刷电路板(PCB)图像预处理中,图像分割和图像增强是非常关键的步骤,直接影响以后的图像处理。作者利用灰度直方图的统计特性,提出了一种搜索前景和背景峰值点、极小阈值点的方法,是文献[1]算法的改进,可以很好的进行图像分割和增强。实验证明,通过这种方式处理的图像分割、增强效果很好。
In the pre-processing of PCB images, image segmentation and enhancement is important, and effects directly image processing. Using image statistics characteristic of histogram, author provides a method that search threshold value, foreground and background peak value, which improved the algorithm of [1]. Experimental results show that one can obtain better segmentation and enhancement of image by using this approach.
