*************************************************************
From Codes To Cognition
Foundational Aspects of
Visual Information Processing
Centennial Conference
in Honour of Hermann v.Helmholtz
***********************************************************
University of Kiel/Germany
17.-21. July 1994
Organized by
Dieter Heyer & Rainer Mausfeld
Funded by
Deutsche Forschungsgemeinschaft
The conference will address fundamental psychological problems of
visual perception in areas such as shape from shading, stereo vision,
colour and form perception and attention. A basic theme recurring
throughout the conference will be how perceptual achievements relate
to sensory input. Since Helmholtz and his notion of "unconscious
inferences", several theoretical intuitions (e.g. the concept of
"ill-posed problems", Barlow's statistical model for the discovery
of "independent coincidences", Ullman and Koenderink's discussion
of Gibson's idea of "direct perception", Hoffman's "observer
mechanics", Shepard's ideas on resonance) concerning the principles
of perception have revolved around the attempt to bridge the gap
between the (often 'meagre') sensory input and the actual performance.
The conference will focus on attempts to theoretically understand the
interaction of
- restrictions and invariants of the physical environment,
- theoretical limiting factors of the sensory system as well as
- restrictions on the categorization and interpretation of sensory
information that have been internalized in the course of evolution.

FORMAT OF THE CONFERENCE:
INVITED SPEAKERS ONLY, no parallel sessions, ample time for discussions.
Unlike other conferences the aim of the Helmholtz Conference will
be to present a resume of the state-of-the-art of the field and
its foundational problems and challenges. As befits the occasion,
presentations at the Helmholtz Conference will address a wider scope of
fundamental psychological problems of visual perception. Rather than
giving mere technical presentations of current empirical findings,
lectures will point out which classical questions are still unsolved,
which conceptual problems are often hidden behind apparently clear facts,
and discuss tacit assumptions of present research perspectives.
LOCATION:
The conference will take place at Kiel University, one of the oldest
German universities. Kiel is a middle sized town in the north of Germany
and nicely situated on the shores of the Baltic Sea. It just one hour
away (car, train) from Hamburg and can be reached by plane from
Frankfurt and Cologne.

ACCOMMODATION:
All invited speakers will reside in a first-class hotel right on the
shores of Kiel firth. We have managed to obtain special rates (145 DM
for a single room/190 DM for a double room) for a small additional
contingent of rooms at this hotel and these rooms will be allocated on
a first come first served basis.
Addresses of other hotels and guesthouses will be sent (by e-mail only)
on request. Since Kiel is a famous holiday and sailing resort during the
summer, it is advisable to book accommodation early.
