Abstract
We propose new methods
for auditory display (AD) and sonification of textured images
(Rangayyan, Martins & Ruschioni, 1996), in particular of MRI
images, as an adjunct to visual examination of the images. We
consider two models for textured images: ordered or (quasi-)
periodic texture, where a basic texture element or texton is repeated
over the image field; and random texture, which could be modeled
as filtered spot noise. MRI images would match the latter model.
Our AD and sonification algorithms incorporate analogies between
the two types of texture mentioned above, and voiced and unvoiced
speech.
