摘要
针对线性扩散在图像去噪中的不足,提出了基于方向扩散的线性扩散图像去噪方法.该方法对图像进行线性扩散的同时,具有保护图像边缘的作用.实验表明本算法在去除噪声和信噪比上取得了较好的效果.
This paper identifies the defects in the image de - noising of linear diffusion and advances a new image de - noising method of linear diffusion based on the directed diffusion. The new scheme can protect the edges of image in linear diffusion process. Experimental results show that the algorithm achieves better effect in removing image noise and SNR.
