| 摘 要： | 在频域滤波的基础上,对图像的高频部分进行噪声识别,区分边缘与噪声,进而通过改进的空间滤波算法实施去噪,使图像边缘细节部分得到保护,再将处理后的高频图像与其对应的低频图像进行融合,以获得完整的高质量图像.实验结果表明通过新算法处理后的图像可以达到较好的降噪效果.

| Abstract: | On the base of frequency domain filtering,the new algorithm identified the noise in high-frequency portion of the image was set forth,distinguished edge and noise,thereby to reduce noise through the improved algorithm of spatial filtering,and to protect the edge of the image.The treated high-frequency image was fused with its corresponding low-frequency image,to obtain a complete and perfect image.Experimental results showed that the new algorithm can achieve the purpose of the image noise reduction. |
