图像处理技术在解决曝光不足问题中的应用

本文运用数字图像处理技术,针对曝光不足问题,提出了灰度变换法和直方图修正法,通过软件编程进行了验证。结果表明,经过处理的图片亮度和对比度有了明显增强。

Based on digital image processing technique,the paper brings forward gray algorithm and histogram modification algorithm which were post focus on the underexposure. Programming turned out that the brightness and contrast of the processed pictures were improved obviously,the image resolution was raised.
