一种基于亮度保持的图像增强方法

A Method for Image Enhancement Based on The Brightness Preservation

摄像头采集到的图像容易受到外部光照变化变得模糊,导致图像中的对象无法清晰的辨别。针对这一问题,通过对安防系统中的图像特性进行研究,本文提出和设计了一种基于图像直方图模型的亮度保持的图像增强算法,该算法采用分段常数直方图模型原理实现对图像的亮度保持的同时来提升视频图像的质量。通过实验证明本文提出的算法在算法效率、图像亮度保持等方面相对于经典的图像增强算法具有明显的优势。

In an image captured by a video camera,the object,susceptible to external illumination variation,can be indiscernible.To settle the problem,through the analysis of the image properties in a security system,an algorithm concerning image enhancement by preserving brightness based on the model of image histogram is proposed,in which the quality of the images in video is enhanced by preserving brightness based on the principle of piecewise constant image histogram.In this experiments,the proposed algorithm demonstrates its clear superiority over the traditional methods regarding algorithm efficiency and image brightness preservation.
