摘要：图像增强是指按一定的需要突出一幅图像中的某些信息，同时削弱和去除某些不需
要的信息，使之改善图像的质量，加强图像判读和识别效果的处理技术，论文在介绍图像
频域增强原理的基础上，在频域内通过对低通滤波器、高通滤波器的图像增强进行了研究，
介绍了相关的理论和数学模型，并利用 MATLAB 工具进行实现。实验证明，低通滤波器
和高通滤波器都能较好的改善图像质量。
Abstract:Image enhancement means according to certain need to highlight a picture
of some of the information, and weaken and remove some don't need information,
to improve image quality and enhance the image interpretation and recognition
effect, the paper introduces the processing image frequency domain enhancement,
the basis of the principle of in frequency domain of low pass filter through the
image enhancement, high-pass filter was studied, introduced the related theory
and mathematical model, and use of MATLAB tools for implementation. Experimental
proof, low-pass filter and high-pass filter can better improve image quality.
Keywords: Image enhancement Low-pass filtering High-pass filtering
