Visualization of Time-varying Scientific Data through Comparative Fusion and Temporal Behavior Analysis

Visualization of time-varying scientific and medical datatraditionally has been done through animation or a series of still
frame renders. Animation and still frame comparison is only minimally
sufficient, due to limitations, such as short term visual memory and
the lack of analytical feedback, to effectively find and compare
temporal trends. To improve time-varying analysis, several
different visualization methods are described. For direct visual
comparison of individual time steps, we introduce a rendering
technique that fuses multiple time steps into single data, by
projection and composition methods. This can be achieved through
projection along time, and further generalized to high dimensional
space-time projection. Furthermore, time volumes (or multivariate
data) can be compared through composition and set operations. To aid
in the understanding of comparative time volumes, focus+context
animation is used to reveal features in the data, by utilizing human
motion perceptual capabilities. In addition to comparative and
highlighting techniques, we also provide the quantitative analysis of
time-varying data via time behavior classification. We allow a user to
visualize and explore their time-varying data as classes of
multi-scale temporal trends. Also through the analysis of the time
activity, we can also semi-automatically generate classifications
(transfer functions) to be used in the visualization pipeline.
