Structural image interpolation using a nonlinear second-order hyperbolic PDE-based model
Tudor Barbu · 2017
An effective structure based image completion framework is provided in this article. The proposed technique uses a nonlinear second order hyperbolic partial differential equation (PDE) - based model that is based on a properly constructed edge-stopping function and an image mask corresponding to the inpainting zone. The hyperbolic model is then discretized using a consistent explicit finite difference-based numerical approximation scheme. The described approach inpaints successfully the missing regions and also reduce the additive (Gaussian) noise and the unintended effects.
