  abstract =   "Transfer functions have a crucial role in the understanding
               and visualization of 3D data. While research has scrutinized
               the possible uses of one and multi-dimensional transfer
               functions in the spatial domain, to our knowledge, no
               attempt has been done to explore transfer functions in the
               frequency domain. In this work we propose transfer functions
               for the purpose of frequency analysis and visualization of
               3D data. Frequency-based transfer functions offer the
               possibility to discriminate signals, composed from different
               frequencies, to analyze problems related to signal
               processing, and to help understanding the link between the
               modulation of specific frequencies and their impact on the
               spatial domain. We demonstrate the strength of
               frequency-based transfer functions by applying them to
               medical CT, ultrasound and MRI data, physics data as well as
               synthetic seismic data. The interactive design of complex
               filters for feature enhancement can be a useful addition to
               conventional classification techniques.",
