Abstract
The traditional aids for vision impairment
normally rely on tactical or sound perceptions to
partially restore the quality of daily activities. It is our
goal to pursuit An Adaptive Digital Vision Aid for
Low Vision, especially those caused by cataract and
macular degeneration diseases. This system not only
provides the traditional monochromatic high contrast,
brightness, field adjustment and necessary enlargement
but also optimally compensates each individual’s
visual loss according to the measurement of his/her
own contrast sensitivity function (CSF). The features of
wavelet transform can allow the applications to both
text and color images, which certainly increases the
quality of visual perception.
