||Retrieval of Digital Shapes by Size Functions
||Dott. Daniela Giorgi
The recent increased usage of image and multimedia databases has
motivated research in building tools to automatically extract the
geometric, and possibly semantic, content of digital shapes. The goal
is the development of effective content-based search engines to browse
the Web or digital objects repositories.
In this talk I will recall some basic concepts about Size Functions,
which are a mathematical tool suitable for shape description and
comparison. I will then examine how Size Functions can be applied in
the field of digital shape analysis and retrieval. In particular, the
attention will be focused on the problem of retrieving figurative images
and three-dimensional models from large databases.
