基于MATLAB的图像处理空间域滤波研究

Research of Image Spatial Domain Filtering Based on MATLAB

为改善原始图像清晰度差、提高图像视觉效果,采用空间域图像滤波方法。该方法相比时域滤波方法,虽然算法复杂,但可使图像获得更好的视觉效果。运用MATLAB软件对原始图像进行平均平滑、高斯平滑、中值滤波及基于一阶和二阶微分的锐化算子进行一系列处理,分析了每种处理方法的优缺点。实验结果显示:采用空间域的图像滤波方法不仅具有良好的去噪效果,而且可以极大改善原始图像质量。

Aiming at how to improve the original image and improve the visual effect in image processing. In this paper, tht, spatial domain image filtering method, compared with the time domain filtering method,ahhough the algorithm is more complex, but can make the image to get a better visual effect. The use of the original image is the average smoothing, Gauss smoothing, median filtering and sharpening operator of one order and two order differential hased on a series of Matlab software,and analyzes the advantages and disadvantages of each treatment. The cxperimental results show that the image spatial filtering scheme not only has good denoising effect, but also can improve the quality of the original image of the great.
