Abstract

Advanced 3D microstructural analysis in natural sciences and engineering depends ever more on modern data
acquisition and imaging technologies such as micro-computed or synchrotron tomography and interactive visualization.
The acquired volume data sets are not only of high-resolution but in particular exhibit complex spatial
structures at different levels of scale (e.g. variable spatial expression of multiscale periodic growth structures in tooth enamel). Such highly structured volume data sets represent a tough challenge to be analyzed and explored
by means of interactive visualization due to the amount of raw volume data to be processed and filtered for the
desired features. As an approach to address this bottleneck by multiscale feature preserving data reduction, we
propose higher-order tensor approximations (TAs). We demonstrate the power of TA to represent, and highlight
the structural features in volume data. We visually and quantitatively show that TA yields high data reduction and
that TA preserves volume features at multiple scales.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
