摘　　要：图像增强是数字图像处理的重要内容,它通过改变图像的灰度分布来改善图像的质量。本文讨论了基于直方图均匀处理的图像增强技术基本原理,并在传统的直方图均匀算法中加入了线性灰度变换。同时以一个灰度图像为例,在Java开发环境下实现了直方图均匀化并线性拉伸的处理。实验结果表明,该方法有效地增强了图像的质量也降低传统直方图均匀化处理导致图像细节丢失对图像质量的影响。Image enhancement is an important part of digital image processing.It improves the image quality by changing the gray distribution of the image.In this paper,the basic principle of image enhancement technology based on histogram uniform processing is discussed,and linear gray transformation is added to the traditional his-togram uniform algorithm.At the same time,a gray image is taken as an example to realize histogram homogeni-zation and linear stretching under the Java development environment.The experimental results show that the method can effectively enhance the image quality and reduce the impact of image detail loss caused by traditional histogram homogenization processing on image quality.
