A Texture Synthesis Approach to Euler's Elastica Variational Inpainting
Abstract
We present a new automatic technique for wire and scratch removal
(inpainting) that works well in both textured and non-textured areas
of an image. Chan, Kang, and Shen introduced a technique for
inpainting using an Euler's elastica energy-based variational model
that works well for repairing smooth areas of the image while
maintaining edge detail. The technique is slow, due to a stiff 4th
order PDE solution. Efros and Leung's texture synthesis techniques can
be used for inpainting, which works well for areas of an image that
contain repeating patterns. We have combined these two techniques to
accelerate and constrain the solution of the 4th order PDE. Instead of
a stiff minimization, we have a combinatorial optimization problem
that is much quicker to solve and more stable.
This is a joint work with Doug Roble from Digital Domain and Tony Chan
from UCLA.
