Creem-Regehr, Sarah Hope; Gooch, Amy A.; Sahm, Cynthia S.; Thompson, William B. | Perceiving virtual geographic slant: action influences perception | Four experiments varied the extent and nature of observer movement in a virtual environment to examine the influence of action on estimates of geographical slant. Previous slant studies demonstrated that people consciously overestimate hill slant but can still accurately guide an action toward th... | Geographical slant; Virtual environment | 2003-06-16 |

Baxter, Brent S. | Image processing in the human visual system | This work extends the multiplicative visual model to include image texture as suggested by experiments [Campbell, Weisel] linking a low resolution Fourier analysis with neurons in certain parts of the visual cortex. The new model takes image texture into account in the sense that weak texture is acc... | Human visual system; Image texture | 1975 |

Shirley, Peter S. | Natural image statistics for computer graphics | The class of all natural images is an infinitely small fraction of all possible images. The structure of natural images can be statistically modeled, revealing striking regularities. The human visual system appears to be optimized to view natural images, as opposed to any possible image, and therefo... | Natural image | 2001 |

Faugeras, Olivier Dominique | Digital color image processing and psychophysics within the framework of a human visual model | A three-dimensional homomorphic model of human color vision based on neurophysiological and psychophysical evidence is presented. This model permits the quantitative definition of perceptually important parameters such as brightness. saturation, huo and strength. By modelling neural interaction in t... | Human visual model; Neurophysiological evidence; Psychophysical evidence | 1977 |

Freire, Juliana; Silva, Claudio T. | VisMashup: streamlining the creation of custom visualization applications | Visualization is essential for understanding the increasing volumes of digital data. However, the process required to create insightful visualizations is involved and time consuming. Although several visualization tools are available, including tools with sophisticated visual interfaces, they are o... | VisMashup; Dataflow; Visualization systems; Mashups; Medleys | 2009-11 |

Lefohn, Aaron; Kniss, Joe; Hansen, Charles D.; Whitaker, Ross T. | Interactive deformation and visualization of level set surfaces using graphics hardware | Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization for applications such as segmentation, surface process- ing, and surface reconstruction. Their usefulness has been limited, however, by two problems. First, 3D level sets are relativel... | Interactive deformation; Deformable isosurfaces; Level-set methods | 2003-04-16 |

Lefohn, Aaron; Cates, Joshua E.; Whitaker, Ross T. | Interactive, GPU-based level sets for 3D brain tumor segmentation | While level sets have demonstrated a great potential for 3D medical image seg- mentation, their usefulness has been limited by two problems. First, 3D level sets are relatively slow to compute. Second, their formulation usually entails several free parameters which can be very difficult to correc... | Level sets; Medical imaging; 3D brain tumor segmentation | 2003-04-16 |

Evans, David | Display of complex three dimensional finite element models | Complex three dimensional models can be displayed after an automatic generation of a finite element (panel) mapping. although this automatic generation algorithm fails at certain levels of model complexity, the elimination of these failures can be accomplished through user interaction. This report p... | Three dimensional models; Finite element models | 1978 |

Henderson, Thomas C. | A survey of dextrous manipulation | The development of mechanical end effectors capable of dextrous manipulation is a rapidly growing and quite successful field of research. It has in some sense put the focus on control issues, in particular, how to control these remarkably humanlike manipulators to perform the deft movement that we t... | Dextrous manipulation | 1986 |

Hansen, Charles D. | Gaussian transfer functions for multi-field volume visualization | Volume rendering is a flexible technique for visualizing dense 3D volumetric datasets. A central element of volume rendering is the conversion between data values and observable quantities such as color and opacity. This process is usually realized through the use of transfer functions that are prec... | Volume rendering; Transfer functions; Volume visualization | 2003 |
