| 摘 要： | 由于图像噪声会对后续的图像处理结果产生影响,所以在对图像进行其他处理前应先对图像去噪。针对传统中值滤波器在去除均匀分布椒盐噪声时效果并不理想,设计出一种自适应阈值中值滤波器。分别用两种滤波器进行图像去噪实验,通过对比去噪后图像的信噪比、峰值信噪比以及视觉效果发现:较之传统的中值滤波器,新的自适应中值滤波器能更有效地去除椒盐噪声并减少图像失真。

| Abstract: | As a result of the interference of noise,the results of the following processing will be affected.Hence,before dealing with other image processing,this paper first denoises the image.The conventional medial filters do not perform well in case of uniformly distributed salt & pepper noise,so a new adaptive median filter is presented.By comparing SNR,PSNR and visual effects of the denoised image,it showes that comparing with the conventional median filter the new filter performs better in removing the noise an... |
