摘要
图像增强的目的是要改善图像的视觉效果,加强图像判读和识别效果,满足某些特殊分析需要。MATLAB实现图像增强方式分为空域法和频域法,阐述了对比度增强、直方图均衡化、巴特沃斯滤波等方法,并进行了对比。图像经过处理之后,提高视觉效果,突出重要位置并弱化不需要的细节,使计算机容易处理。
The purpose of image enhancement is to improve the visual effect of the image,to enhance the imageinterpretation and recognition effect,to meet the needs of some special analysis. This paper mainly introduces themethod of image enhancement using MATLAB,which is divided into airspace method and frequency domainmethod. It mainly introduces contrast enhancement method,histogram equalization method and Butterworth filtering method,and makes a simple comparison. After image processing,the visual effect is good,highlighting theimportant position or weakening does not require details,making the computer easy to handle.
