Characterizing Local Features of Illuminated Objects
of visual clues.
These clues follow from the interplay of geometric features
edges and corners, delineating curves on object surfaces, and
illumination such as shadow curves and specularity.
viewer gains such
information not just from static images but also from perceived
change in viewing direction.
In this talk, we explain how it is possible to determine a

Such a catalog is constructed through the use of
