摘要
本文提出一种新的直方图规定化算法,此算法基于高斯函数,处理效果明显优于直方图均衡化算法,而且计算量小、处理速度快、不需要人工干预,可用于计算资源有限、实时性要求较高的场合。而且提供了通过改变单一参量控制输出图像的对比度,在工程应用中为用户提供了调控与选择手段。
This paper proposes an algorithm of histogram specification based on Gaussian PDF, which is much better than histogram equalization. It also has many advantages over other algorithms of image enhancement, such as low computing quantity, high efficiency and no manual interview. It can be used in the cases that have limited compute resource and real time operation. The algorithm also provides a way to easily control the contrast of the output images by alternating only one parameter.
