文档介绍：摘要
图像处理着重强调在图像之间进行变换,包括:图像采集和获取、图像重建、
图像变换、图像滤波、增强、恢复或复原、图像压缩编码等。其中图像增强是提
高图像视觉质量的重要手段,所完成的工作包括去除图像噪声,增强图像对比度
等。这里只介绍了频域增强技术。
本文主要介绍了理想、巴特沃斯( Butterworth)、指数和梯形四种各自的低
通和高通滤波器的基本原理和技术方法,通过实例分析了它们对图像进行增强处
理后的结果并且比较了它们各自的优缺点。

ABSTRACT
Image processing emphasized how to transform between images, including: image
acquisition and procurement, image reconstruction, image converter, image filtering,
enhance, restore or recovery, pression, etc. Which image enhancement is to
improve the Visual quality of the image as an important means of pleted,
including the removal of image noise, enhance image contrast, etc. Here only describes
frequency enhancement technology.
KEY WORDS: Low-pass filter, high pass filter, the transfer function
