A gradient based neighborhood filter for disparity interpolation

Published: Sept. 1, 2012

In this work we propose a non-local gradient-based energy for interpolating incomplete disparity maps. It represents an extension of the bilateral filter adapted to reconstruct locally planar We assume that have at our disposal reference image from which similarity weights can be computed. When spatial extend tends zero, proposed model shown converge involving second order derivatives, explaining thus its ability obtain higher interpolations. The minimized by solving Euler-Lagrange equation via iteration Poisson equations. By including edge map permits also recover depth discontinuities.
