Title: Inpainting and Visual Interpolation

Abstract
Inpainting, or image interpolation, has broad applications in visual 
perception, digital media, and information technology. Compared with other 
classical interpolation problems (such as polynomial-, spline-, Shannon- 
or wavelet-interpolations), inpainting imposes extra challenges mainly due 
to the complexity of both missing domains and missing signals, especially 
the geometric features of images. In this talk, we focus on our recent 
efforts in applying the variational-PDE approach to inpainting, and reveal 
novel intriguing applications of nonlinear PDEs, geometric measure theory, 
and Gamma-convergence in mathematical imaging and vision. (Joint work with 
several authors in a series of papers, especially with the applied math 
group at UCLA.)
