8-5 Total-Variation正則化を用いた超解像度デモザイキング法の一検討(第8部門 画像入出力技術・他)

抄録

Previously we have presented the sharpening-demosaicking method with the total-variation (TV) based super-resolution. The TV-based super-resolution effectively suppresses ringing artifacts around salient edges, but it excessively flattens original signal variations in texture regions. This paper presents a scheme that controls the TV-based super-resolution adaptively according to the magnitude of color edges around a pixel to be processed.
