This paper describes the process of building a GIS for use in real time by blind travellers. Initially the components of a Personal Guidance System (PGS) for blind pedestrians are outlined. The location finding and database components of the system a

Primary selection plays a fundamental role in display design. Primaries affect not only the gamut of colors the systems is able to reproduce, but also, they have an impact on the power consumption and other cost related variables. Using more than the

A Visual Model (VM) is used to aid in the design of an Ultra-high Definition (UHD) upscaling algorithm that renders High Definition legacy content on a UHD display. The costly development of such algorithms is due, in part, to the time spent subjecti

A modification to the standard Bayer CFA and photodiode structure for CMOS image sensors is proposed, which we call 2PFC™, meaning “Two Pixel, Full Color”. The blue and red filters of the Bayer pattern are replaced by magenta filters. Under eac

While the use of visual models for assessing all aspects of the imaging chain is steadily increasing, one hindrance is the complexity of these models. This has impact in two ways - not only does it take longer to run the more complex visual model, ma

We outline the design for a navigation system for the visually impaired and describe the progress we have made toward such a system. Our long-term goal is for a portable, self-contained system that will allow visually impaired individuals to travel t

The authors consider auditory distance perception of a moving observer and its relevance for the perception of stationary and moving sources. They begin with a review of some of the acoustic cues to source distance, focusing on the dynamic cues avail

Achromatic adjustment has been used widely to study color context effects. In the achromatic adjustment procedure, an observer adjusts a test stimulus until it appears black, gray, or white. By its nature, achromatic adjustment directly measures the
