Dear colleagues,

the Trieste Symposium on Perception and Cognition and the 27th Kanizsa
Lecture will take place at the University of Trieste, November 8, 2019,
starting at 9.00 am.

Traditionally, the Symposium is open to all perspectives and approaches,
has no registration fee, and runs on an informal, relaxed pace.

This year the Kanizsa Lecture will be delivered by prof. Roberto Casati
(Institut Jean Nicod, CNRS, France, Paris) on Friday 8 November, starting
at 4.00 pm.

The 27th Kanizsa Lecture

Shadows in vision

Roberto Casati
Director
Institut Jean Nicod

Renaissance painters knew perspective, and mastered chiaroscuro. Cast
shadows are chiaroscuro in perspective, so why did it take them a century
to master the depiction of cast shadows? (Leonardo's Treatise is a
fascinating compilation of strategic errors that block the solution.)
Although Gestalt psychologists were keen on phenomenal objects, they
nevertheless overlooked cast shadows and missed out on the rules presiding
their parsing in the visual scene. (I won't even dare mention philosophers,
who had shadows under their lens since Plato and could have made a lot of
their representational properties. They didn't.)
Building on common work with Patrick Cavanagh (The visual world of shadows,
MIT Press 2019) I will present a view of the computational rules that
govern shadow perception, from shadow labeling to ownership to the
reconstruction of visual layout. I'll focus in particular on ownership, an
interesting case study for the application of gestalt rules across
categories of objects. I hope to convey the great heuristic power of
shadows for vision science. Shadows may have been neglected or
misinterpreted by psychologists, painters and philosophers, but they surely
have not been slighted by the visual system, that has been able, in its
long evolutionary history, to turn the noise they create into robust
knowledge.

If you wish to contribute a presentation, please submit your proposal by
electronic mail to trieste.symposium at gmail.com (specifying whether you
prefer a talk or poster). Each proposal should be submitted as an abstract
(250-400 words). Proposal will be evaluated by a scientific committee.
