Nonlinear Diffusion-based Image Restoration Model

摘要

A novel nonlinear PDE - based image denoising and restoration approach is provided in this article. The proposed anisotropic diffusion based technique is derived from the influential Perona-Malik nonlinear diffusion scheme, representing an enhanced version of that scheme. Our model is based on new versions of the edge-stopping function and the conductance parameter. The proposed PDE-based filtering technique performs an efficient edge-preserving noise removal, outperforming the conventional smoothing approaches and other PDE denoising models.
