Abstract : We present a PDE-based interpolation algorithm to effectively reproduce high resolution imagery.Conventional PDE-based interpolation methods can produce sharp edges without checkerboardeffects; however, they are approximators and tend to weaken fine structures. In order toovercome the drawback, a texture enhancement method is incorporated as a post-process ofPDE-based interpolation methods. The post-process turns out to make the resulting algorithman interpolator. It has been numerically verified that the resulting algorithm, called the PDEbasedimage interpolator (PII), restores sharp edges and enhances fine structures satisfactorily,outperforming the PDE-based skeleton-texture decomposition (STD) approach.
