    • In this paper, the question of automatically setting transfer functions for volume images is further explored. Morespecifically, the focus is automatic visualization of Molecular Electron Tomography (MET) volume images usingone-dimensional transfer functions. We investigate how well a few general measures based on density, gradient,curvature and connected component information are suited for generating these transfer functions. To assessthis, an expert has set suitable transfer function levels manually and we have studied how these levels relate todifferent characteristics of the selected measures for 29 data sets. We have found that the measures can be used toautomatically generate a transfer function used to visualize MET data, to give the user an approximate view of thecomponents in the image.

  • Towards automatic visualization of MET biomedical data

  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • This work describes a starting point for estimationof parameters when visualizing Molecular ElectronTomography (MET) volumes. The aim is to instantly and automatically produce an initial rendering of the biological molecules in a MET volume. A one-dimensional transfer function with fixed primitives is suggested to highlight the structure and interaction of the molecules. The correlation between manually set parameters by an expert user for these primitives and measures related to topology, gradient and curvature are explored. The work is part of the ProViz project aiming at creating better tools for analysis and hapto-visualization of MET volumes of proteins
