Saliency algorithms provide a measure of which sections in an image
are important or informative. This can be valuable to digital
artists who wish to produce works that build layers of abstraction
or augmentation onto an input image. Using a framework
based on the Texture-Illumination Guided Global Energy Response
(TIGGER) to access two types of saliency measurements, a multidisciplinary
projection project, Nebula, has been produced, in which
starscapes are created in near real time from depth images.
