摘要:

我们提出了一套迭代正则化算法的TV-Stokes模型恢复图像从噪声图像与高斯噪声。这些是经典的Rudin-Osher-Fatemi(ROF)图像重建模型的迭代正则化算法的一些扩展,ROF模型是一个涉及标量场平滑的单步模型,TV-Stokes模型是一个涉及第一步中的向量场平滑和第二步中的标量场平滑的两步模型。这里提出的迭代正则化算法是Richardson迭代。我们的实验结果表明,在原始方法的恢复图像的质量有所改善。收敛性分析和数值实验。

英文摘要:

We propose a set of iterative regularization algorithms for the TV-Stokes model to restore images from noisy images with Gaussian noise. These are some extensions of the iterative regularization algorithm proposed for the classical Rudin-Osher-Fatemi (ROF) model for image reconstruction, a single step model involving a scalar field smoothing, to the TV-Stokes model for image reconstruction, a two steps model involving a vector field smoothing in the first and a scalar field smoothing in the second. The iterative regularization algorithms proposed here are Richardson's iteration like. We have experimental results that show improvement over the original method in the quality of the restored image. Convergence analysis and numerical experiments are presented.
