摘 要: | 为了有效消除或尽量减少噪声的影响,改善图像的品质,分别对空域均值滤波、空域中值滤波、频域低通滤波三种方法以及对图像平滑技术进行了深入研究.综合而言,频域低通滤波具有更好的选择性,对噪声在一定范围内也可以起到抑制作用,同时也对图像的边缘细节和高频信息分量有更好的保持作用.

Abstract: | In order to effectively eliminate or minimize the impact of noise to improve image quality,airspace mean filter,air space,median filtering,frequency domain low-pass filter three methods,in-depth study of image smoothing techniques.Overall,the frequency domain low-pass filter has a better selectivity,noise within a certain range can also play an inhibitory effect,but also on the edge of the image details and high-frequency component of information to better maintain. |
