精品文档---下载后可任意编辑论文题目： 数字图像处理图像增强算法的讨论学 院： 计算机与信息学院班级：软件 141 姓名：程健学号： 3140704135 指导老师：卢桂馥2024 年 6 月 9 日精品文档---下载后可任意编辑摘要在我们的实际生活、生产中，人们直接获得的原始图像并不能够直接运用到生活、生产中，因为原始图像在生成、 传输和转换过程中可能会受到多种因素的影响，如各种各样的噪声、通道带宽等，往往会出现清楚度下降、对比度偏低等降质现象，为了使得处理后的图像对某种特定的应用比原始图像更合适，往往需要提高图像质量。图像增强是指按特定的需要突出一幅图像中的某些信息，同时削弱或去除某些不需要信息的处理方法，其目的是使得处理后的图像对某种特定的应用比原始图像更合适。本文讨论了图像增强的一些常用方法， 包括空域图像增强、 频率域图像增强， 并用MATLAB 编程设计了相应的实验，对图像增强效果进行了验证。关键字：图像增强；图像；算法；空域增强；频率增强AbstractIn our daily life and production, people often can't used the raw image directly, because of the generation and transformation of the original image, it may be affected by many factors, such as a variety of kinds of noise and channel bandwidth. The sharpness and contrast is decreasing and have low qualities. in order to make the image more suitable for some particular application after processing than the original, we often need to improve image quality. Images enhance is in a particular need to highlight a picture in the information, and weaken or remove certain need of information in the process, its purpose is to make the image of a specific application is better than the original image. This paper studies the image of some common method, including airspace images enhance and increase the frequency domain, and images matlab programming, design corresponding to picture to enhance the effect of the verification. Key words:Image enhancement; the airspace strengthened; the frequency...
