摘要 本文从各向异性扩散图像去噪方法出发,在偏微分方程有限元方法的基础上,提出一种图像复原并放大的 算法,实验表明该算法比中值滤波后插值所得图像的主、客观质量要好。 Based on anisotropic diffusion method for noise removal and numerical solution of partial differential equations, an algorithm is performed for noise removal and image zoom. Experiment result show that this algorithm is valid. Using objective comparisons, we find the former method is better than the latter method in visualization of image.
