We report empirical study results on the color encoding of ensemble scalar and orientation to visualize diffusion magnetic resonance imaging (DMRI) tubes. The experiment tested six scalar colormaps for average fractional anisotropy (FA) tasks (grayscale, blackbody, diverging, isoluminant-rainbow, extended-blackbody, and coolwarm) and four three-dimensional (3D) spherical colormaps for tract tracing tasks (uniform gray, absolute, eigenmaps, and Boy's surface embedding). We found that extended… Expand
Evaluating Gradient Perception in Color-Coded Scalar Fields
The results support a hypothesis that apparent discontinuities in the color ramp may help viewers discern subtle structural differences in gradient, and highlight future research directions for colormap evaluation. Expand
What Do People See in a Twenty-Second Glimpse of Bivariate Vector Field Visualizations?
Empirical study results on the use of color, texture, and length to guide viewing of bivariate glyphs suggest that using categorical visual feature could help obtain the global structure of a vector field visualization. Expand


Effects of illumination, texture, and motion on task performance in 3D tensor-field streamtube visualizations
Results from a user study of task performance on streamtube visualizations can help in the design of lighting model, such as flow or diffusion-tensor field visualizations and identify situations when the lighting is more efficient and accurate. Expand
Color schemes to represent the orientation of anisotropic tissues from diffusion tensor data: application to white matter fiber tract mapping in the human brain
Directionally encoded color (DEC) maps of the human brain obtained using empirical or heuristic schemes clearly show the main association, projection, and commissural white matter pathways. Expand
Effects of Stereo and Screen Size on the Legibility of Three-Dimensional Streamtube Visualization
It is found the task completion time was not improved by the use of the larger display and that performance accuracy was hurt rather than helped by the introduction of stereo in the study with dense DMRI data. Expand
Visualizing Diffusion Tensor MR Images Using Streamtubes and Streamsurfaces
Expert feedback from doctors studying changes in white-matter structures after gamma-knife capsulotomy and preoperative planning for brain tumor surgery shows that streamtubes correlate well with major neural structures, the 2D section and geometric landmarks are important in understanding the visualization, and the stereo and interactivity from the virtual environment aid inUnderstanding the complex geometric models.

Hue-balls and lit-tensors for direct volume rendering of diffusion tensor fields
Direct volume rendering is proposed, with novel approaches for the tensors' coloring, lighting, and opacity assignment based on a novel two-dimensional barycentric space of anisotropy, to produce informative renderings of measured diffusion tensor data from the human brain. Expand
Effects of ensemble complexity and perceptual similarity on rapid averaging of hue.
It was found that averaging was harder for ensembles with more colors but that changing the number of elements had no effect on accuracy, supportive of a distributed-attention account of rapid color averaging. Expand
Coloring of DT-MRI Fiber Traces Using Laplacian Eigenmaps
It is demonstrated that when the low-dimensional space is the RGB color space, this can be used to visualize fiber traces in a way which enhances the perception of fiber bundles and connectivity in the human brain. Expand
Face-based luminance matching for perceptual colormap generation
This work presents a simple and effective method for performing luminance matching on an uncalibrated monitor, akin to the minimally distinct border technique, but which relies on the brain's highly developed ability to distinguish human faces. Expand
Validation of SplitVectors Encoding for Quantitative Visualization of Large-Magnitude-Range Vector Fields
An empirical study comparing the SplitVectors approach with three other approaches - direct linear representation, logarithmic, and text display commonly used in scientific visualizations shows that Stereoscopy improved performance, especially in more challenging discrimination tasks. Expand
Colorful brains: 14years of display practice in functional neuroimaging
A variety of display styles are demonstrated despite a remarkable dominance of few image production sites and software systems, some tendencies of standardization are outlined, and shortcomings with respect to color scale explication in neuroimages are identified. Expand
