The Application of Multi-grid Method to Smooth Noising Image
Rongcong Xu, Chen Fei · 2007
The PDE-based image restoration has drawn much attention in the recent years. In this paper, we first propose two novel improved models based on the Perona-Malik anisotropic diffusion model and the fourth-order PDE model. Then, we use multi-grid numerical solutions to solve our PDE models. Numerical experiments show that our improved algorithms are efficient and fast convergent.
