基于MATLAB的图像频域增强技术的研究
Research on Technique of Image Frequency Domain Enhancement Based on Matlab
图像增强是指按一定的需要突出一幅图像中的某些信息，同时削弱或去除某些不需要的信息，使之改善图像质量，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、同态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，并给利用MATLAB工具进行实现。实验证明，在质量较差的图像中，选择不同的滤波算法对图像的增强在准确性上均有不同。
Image enhancement aims to stand out some information of a picture to strength image identification and recognization. At the same time it can wipe out the information that we don’t need in order to improve the quality of image. This paper addresses image frequency enhancement principle and also researches low-pass filtering, high-pass filtering and homostasis filtering. While it introduces the relative theory and maths model and realized them using MATLAB. The experiments indicates that different filtering have different enhancement accuracy for the bad quality picture.
