Summary on Grant Application Form |
|
A range of visual cues mediate human depth perception, including pictorial cues (relative size, interposition, perspective, etc) and binocular steriopsis. The perceptual research in this proposal will examine the extent to which image blue is used as a depth cue. Images of 3-D scenes formed by cameras and by eyes necessary contain variations in blue, due to depth-of-focus limitations. The precise, quantitative relationship between blue extent and distance from the point of focus provides a potentially very powerful cue to distance, but there has been no systematic research on the use of blur as a depth cue. A programme of experiments will measure the ability of human observers to detect differences in image blur, and will assess the precision with which observer use blue variation as a cue to distance, both in isolation and in combination with other depth cues.Results will have potential applications in information technology, because they will indicate how blue can be added to introduce a realistic impression of depth in computer-generated images (eg virtual reality), and they will offer guidance on the use of blur as a way of introducing apparent depth separation between elements in the image (eg multiple windows in graphical user interfaces).
