摘要
基于常用的灰度变换法和直方图均衡化法等图像增强算法,提出了一种对比度增强算法。该算法首先对直方图进行平滑处理,再进行直方图均衡化,然后在整个显示范围内对图像灰度级进行等间距排列,最后对图像进行中值滤波去除噪声。实验表明该技术能够使图像的细节和清晰度得到明显的增强。
Based on the common use image enhance algorithm such as gray level transformation algorithm and histogram equalization algorithm, an improved contrast enhancement algorithm was suggested. At first, the smoothness processing was carried out in histogram; at second, the histogram was equalized; at third, the uniform piston queuing was carried out for image grey degree in whole display area; at last, the noise is eliminated through median filtering to the image, The experimental result shows that this algorithm could strengthen the detail and clarity definition of the image.
