Image inpainting based on partial differential equations using diffusion equations, with additional programs implementing CDD (curvature driven diffusions) models for edge-preserving restoration
Detailed Documentation
Image inpainting based on partial differential equations (PDEs) represents a widely adopted methodology that utilizes diffusion equations to restore damaged or missing image regions. Beyond conventional diffusion equations, the CDD (curvature driven diffusions) model offers an advanced alternative that better preserves edge information and fine details through curvature-based diffusion constraints. In practical implementation, standard PDE-based methods typically involve solving heat equations with appropriate boundary conditions, while CDD models incorporate curvature terms to control diffusion rates near edges. Therefore, when performing image restoration tasks, employing both traditional PDE-based inpainting techniques and CDD models can yield superior restoration outcomes, with the latter particularly effective for maintaining structural integrity in complex textured regions.
