摘要: 分析了去灰度冗余的线性灰度变换与基于傅里叶变换的巴特沃斯高通滤波图像增强的基本原理,讨论了它们在图像增强中的实现方法,指出了各自的优点。为了使整体偏暗的印刷电路板(PCB)光电图像更好地增强,提出了结合两者优点的加权平均图像融合增强新方法。对由CCD获取的PCB光电图像进行了实际的图像增强实验,实验结果证明了基本原理分析的正确性。

Abstract: The basic principle of image enhancement of linearity gray transform based on removing redundance gray and Butterworth high-pass filter based on the Fourier transform is analyzed,and their realization methods in image enhancement are discussed,their respective advantages are indicated.In order to enhance the Printed Circuit Board(PCB) photoelectricity images with dark color in whole,a novel method of image enhancement of merging both advantages is proposed.The actual image enhancement experiment is executed by PCB photoelectricity image acquired by CCD,the results of the experiment verifies the correctness of the analysis of the basic principle.

Key words: image enhancement, image fusion, linearity gray transform, gray redundance, Butterworth high-pass filter, Printed Circuit Board(PCB) photoelectricity image
