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. 2012-10-15T00:55:31Z 2012-10-15T00:55:31Z 2012-02-27 Working Paper p. 267-271 978-145771989-9 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6179018 http://hdl.handle.net/123456789/21350 en Proceedings of the International Conference on Biomedical Engineering (ICoBE 2012) Institute of Electrical and Electronics Engineers (IEEE)
