A psychophysically plausible model for typicality ranking of natural scenes
Adrian Schwaninger, Julia Vogel, Franziska Hofer, Bernt Schiele
Natural scenes constitute a very heterogeneous stimulus class. Each semantic category contains exemplars of varying typicality. It is, therefore, an interesting question whether humans can categorize natural scenes consistently into a relatively...
Region-based representations for face recognition
Benjamin J. Balas, Pawan Sinha
Face recognition is one of the most important applied aspects of visual perception. To create an automated face-recognition system, the fundamental challenge is that of finding useful features. In this paper, we suggest a new class of image features...
A perceptually based spectral model for isotropic textures
Danny Holten, Jarke J. Van Wijk, Jean-Bernard Martens
Color is routinely used to visualize interval and ordinal data, while texture is not. For color, a variety of perceptually based models is available, which can be used to convey data via straightforward mapping. The dimensionality of texture is less...
A reality check for tone-mapping operators
Michael Ashikhmin, Jay Goyal
A large number of high-quality tone-mapping operators is currently available. In addition to inherent practical value, comparing their performance is necessary to further advance the field and can provide better understanding of visual realism. In...
Personal space in virtual reality
Laurie M. Wilcox, Robert S. Allison, Samuel Elfassy, Cynthia Grelik
Improving the sense of “presence” is a common goal of three-dimensional (3D) display technology for film, television, and virtual reality. However, there are instances in which 3D presentations may elicit unanticipated negative responses....
Visual calibration and correction for ambient illumination
Kate Devlin, Alan Chalmers, Erik Reinhard
Many applications require that an image will appear the same regardless of where or how it is displayed. However, the conditions in which an image is displayed can adversely affect its appearance. Computer monitor screens not only emit light, but can...
