Studies have shown that the sense of body ownership towards virtual humanoid avatars with additional parts can be successfully elicited when synchronous visuomotor and/or visuotactile feedback is given. In an interactive reality (VR) application, however, it difficult for users to uninterruptedly observe added parts, especially they are attached backs avatars. Thus, embodiment such needs achieved using limited feedback. Commonly, specifically done by looking at a mirror reflection avatar's...

コーヒーの染みなど，目視では識別することが困難な淡い小さな布の汚れを鮮明化する画像処理手法を提案した．汚れが近紫外線で微弱であるが蛍光することを利用して，対象とする布を撮影する際の光源とし，白色LEDおよび近紫外LEDを用いて対象の布を撮影する．撮影画像の各RGB成分画像に対して，スパースコーディングにより求めた基底画像を用いて，テクスチャ構造成分の低減を行う．その後，各画素のRGB成分に対して，白色LEDを光源として撮影した画像と近紫外LEDを光源として撮影した画像との差の3乗を成分とする新たな画像を生成し，それに対して無相関化後，尖度を独立性の評価基準とした独立成分への分解を行う．実験により本手法の有効性を示した．特に，無相関化のみでは，汚れがすべての成分画像に現れるが，独立成分画像に分解することにより，汚れが単一成分画像にのみ現れ，画像成分分解として良好な結果となった．
