Visual content adaptation for low vision users in MPEG-21 framework

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, we present an adaptation framework describing the problem space, and then a systematic contrast-enhancement method to improve the content visibility for low vision users. The experiment results show that the proposed framework and method are effective for the low vision users.
