Abstract
Free-Viewpoint Video (FVV) is a novel technique which creates virtual
images of multiple direction by view synthesis. In this paper,
an exemplar-based depth-guided inpainting algorithm is proposed to
fill disocclusions due to uncovered areas after projection. We develop
an improved priority function which uses the depth information
to impose a desirable inpainting order. We also propose an efficient
background-foreground separation technique to enhance the
accuracy of hole filling. Furthermore, a gradient-based searching approach
is developed to reduce the computational cost and the location
distance is incorporated into patch matching criteria to improve
the accuracy. The experimental results have shown that the gradientbased
search in our algorithm requires a much lower computational
cost (factor of 6 compared to global search), while producing significantly
improved visual results.
