Abstract: Inpainting, the technique of modifying an image in an undetectable form, is as ancient as art itself. The goals and applications of inpainting are numerous, from the restoration of damaged paintings and photographs to the removal/replacement of selected objects. Inspired in part by the work of Masnou and Morel and that of Nitzberg and Mumford, we have developed a number of novel algorithms for digital inpainting of still and video color images. After the user selects the regions to be inpainted, the algorithms automatically fill-in these regions with the information surrounding them. The filling-in is done via high order PDE's or coupled PDE's in such a way that isophote lines arriving at the regions boundaries are completed inside. In contrast with previous approaches, the techniques developed do not require the user to specify where the novel information comes from. This is automatically done (and in a fast way), thereby allowing to simultaneously fill-in numerous regions containing completely different structures and surrounding backgrounds. In addition, no limitations are imposed on the topology of the region to be inpainted. In this talk I will present the models, the underlying theory and connections with Navier-Stokes, and show applications in numerous areas. We will also describe the application of this work to image compression and wireless image transmission.
