and is entitled:

     'tectogen - A new Framework for artistic real-time Music Visualization'

Abstract:

     The artistic fields of real-time music processing and procedural image
     generation are well-established domains in the realm of audiovisual
     performance supported by a substantial body of academic research. 
However,
     real-time music information retrieval techniques have only played a
     peripheral role in these domains and scholarly works are predominantly
     focused on offline music analysis. This presentation attempts an 
overview
     of the various practices of live artistic music visualization as well
     as of established software, such as dataflow languages like Pure Data
     and VJing software like Resolume, contrasting them to the proposed
     "tectogen" software project. tectogen is a prototype of real-time 
artistic
     music visualization software that integrates music information 
retrieval
     techniques into the workflow of visual performers, particularly in 
VJing,
     where synchronization of the viual performance with live music is
     essential. Utilizing a code-generation approach to visualization and a
     user-friendly open source interface, tectogen takes a hybrid approach
     between dataflow languages and VJing software that enables new forms of
     artistic expression. A prospective second presentation will explore the
     theoretical aspects of real-time music information retrieval in the
     context of the tectogen project.

Another talk will be given by

     Tomas Daetz

and is entitled:

     'Isocontours in Uncertain Scalar Fields '

Abstract:

     Uncertainty in data has been one of the main research topics in the 
last
     two decades for the visualization community, as it is a difficult task
     to visualize uncertain data in a meaningful and intuitive way with a
     sound mathematical foundation. Among the data with uncertainty, the
     visualization of uncertain scalar fields has had many advancements,
     especially the analysis of uncertain critical points. Another important
     task for a better understanding of the underlying topology of the 
scalar
     field is the computation of isocontours. Many methods have been 
presented
     to compute and visualize them in the uncertain setting, although most
     methods make some assumptions about the data, e.g., the type of 
underlying
     distribution, and thus limit the correctness of their results, or 
do not
     have a straight-forward extension for showing many isocontours with
     different isovalues. Hence, there is at the moment no general approach
     (i.e., as few assumptions as possible) to compute and visualize 
uncertain
     isocontours. In this talk, previous methods for computing and 
visualizing
     uncertain isocontours will be presented, as well as some ideas on how
     to approach this problem using directly the cumulative distribution
     function.

On behalf of Professor Scheuermann all those interested are cordially
invited to attend.
