【 摘 要 】

In this paper, we propose a visual accessibility techniquein an MPEG-21 framework. In particular, MPEG-21visual accessibility for the colored-visual resource of adigital item is proposed to give better accessibility of colorinformation to people with color vision deficiency (CVD).We propose an adaptation system for CVD as well as adescription of CVD in MPEG-21. To verify the usefulnessof the proposed method, computer simulations with CVDand color adaptation were performed. Furthermore, astatistical experiment was performed using volunteerswith CVD in order to verify the effectiveness of theproposed visual accessibility technique in MPEG-21. Boththe experimental and simulation results show that theproposed adaptations technique can provide better colorinformation, particularly to people with CVD.
