图像增强技术的分析与研究

Analysis and Research of Image Enhancement Technology

图像增强是图像边缘检测、分割以及特征提取等技术的基础,数字图像增强的方法有频域处理法与空域处理法,本文主要介绍空域处理中的灰度变换方法和直方图均衡法。文章首先分析了它们的原理,然后通过MATLAB软件分别用这两种方法对图像进行处理,处理后使图像的对比度得到了明显的改善,增强了图像的视觉效果。

The image enhancement is the technical foundation of image edge examination, the division as well as the characteristic withdraws and so on. Enhanced digital image processing methods has the frequency domain method and the airspace processing method. This paper mainly discussed airspace processing ： gradation transformation method and histogram balancing. It first analyzed their principles, followed by MATLAB software used respectively for the two approaches to image processing, image processing to the contrast gradient markedly improved, thus enhanced the image of the visual effects.
