摘要
讨论了直方图均衡的图像增强原理并对原理进行了证明,介绍了处理数字图像增强的具体过程和算法,以一个对比度较小的图像为实例得到其直方图,按照该算法对图像灰度的直方图进行均衡使其近似均匀分布,处理后图像的对比度得到了明显改善.
This article discusses the principle of histogram equalization for image enhancement and proof of principle were introduced to deal with the specific process of digital image enhancement and algorithms.With a smaller image contrast by the histogram as an example,according to the image gray scale histogram equalization to approximately uniform distribution,treatment significantly improved the image contrast.
