Abstract : This paper deals with the visual content adaptation, in the context of MPEG-21 standard, to help low vision users have better accessibility to the contents. The proposed adaptation targets at two low vision symptoms, loss of fine detail and lack of contrast. Specifically, an adaptation framework and a systematic contrast-enhancement method to improve the content visibility for low vision users are presented. The experiment results show that the proposed method and framework are effective for the low vision users.
