摘要
该文考虑对于原始barbara图像中加入椒盐噪声的图像,得到带有噪声的模糊图像,通过图像去噪得到复原图像.从而考虑在图像处理过程中影响信噪比PSNR的因素.
For the original barbara image with salt-and-pepper noise,the fuzzy image with noise is obtained,and the restored image is obtained by image denoising. Therefore,the factors affecting on signalto-noise ratio(PSNR)in the process of image processing are considered.
