dc.description.abstract | Recently reported Relevant Neighbor Area (RNA) methods for projection image inpainting have achieved a drastic
improvement in reducing inpainting errors simply by excluding irrelevant neighbor pixels in computing an inpainting value. This
research presents how to design more accurate RNA masks in order to further improve the inpainting performance of current
RNA masks. We employ the Intersection of Confidence Intervals (ICI) rule that provides spatially adaptive window size for
optimal signal estimation in the presence of noise. In our case, it allows us to eliminate outlier pixels in RNA that degrades the inpainting performance, yielding an optimal RNA mask. Since the ICI rule gives an optimal neighbor area, we are free from the difficult problem of deciding the size of neighbor area for inpainting. Experimental results show that inpainting methods using more accurately determined RNA masks significantly outperform the methods that employ the current RNA masks. | en_US |
