Abstract: A new noisy image magnification is put forward based on bilateral filtering and edge-directed interpolation,which can preserve edge sharpness and simultaneously denoise defectively.Experimental results show that the proposed method can obtain high accuracy denoises enlarged images.

摘要: 针对含有噪声图像放大中如何有效地保持边缘细节和抑制噪声问题,提出了结合具有保持边缘信息的双边滤波和克服传统插值算法在方块效应和细节退化等方面缺点的边缘方向插值的含噪图像放大方法。实验结果表明该方法能够获得高清晰边缘的去噪放大图像。
