| summary | Traditional vision science takes a relatively simple view
that basic visual attributes such as color, shape, depth and motion
are separately analyzed in early visual cortical areas, with their
outputs being later combined into object representations. Recent
advancement in image processing technology, however, has had us
convinced that the mere combination of the basic visual attributes is
far from sufficient to represent real world visual scenes. Material
perception is the remaining hard problem of sensory science that we
should challenge to fill the gap between our laboratories and the real
world. Most research on human visual recognition focuses on solid
objects, whose identity is defined primarily by shape. In daily life,
however, we often encounter materials that have no specific form,
including liquids whose shape changes dynamically over time. We
recently found that human observers can recognize liquids and their
viscosities solely from image motion flow information, or from dynamic
deformation information. This is the first topic of my talk. In the
latter half, I will talk about cross-modal integration of material
information. For instance, I will discuss how the brain integrates
visual appearance and impact sound when inferring what an object is made from. |
