Evaluating the image quality of Closed Circuit Television magnification systems versus a head-mounted display for people with low vision. .
In this research, image analysis was used to optimize the visual output of a traditional Closed Circuit Television (CCTV) magnifying system and a head-mounted display (HMD) for people with low vision. There were two purposes: (1) To determine the benefit of using an image analysis system to customize image quality for a person with low vision, and (2) to have people with low vision evaluate a t...

متن کاملSimple 1-D image enhancement for head-mounted low vision aid
High-contrast binary images (black and white without shades of gray) were demonstrated to improve face recognition performance by the visually impaired using static images (Peli et al., Invest Ophthalmol Vis Sci 1991;32:2337-2350). A binary head-mounted display device has now been adapted to present video in real time for testing as a low vision mobility aid (an electronic telescope). When used...
