Abstract
We address the problem of analysis of families of shapes
which can be classified according to two categories: the main one corresponding
usually to the coarse shape which we call the function and
the more subtle one which we call the style. The style and the function
both contribute to the overall shape which makes the general analysis
and retrieval of such shapes more challenging. Also there is no single way
of defining the style as this depends much on the context of the family
of shapes used for the analysis. That is why the definition needs to be
given through the examples.
The straight forward way of finding the shape descriptors ’responsible’
for a given category would be to use well known statistical methods and
find through them such descriptors with which we are able to classify
shapes according to a given category. When a function is dominating
this approach might not suffice - we might be unable to find a set descriptors
which are independent of a given function. We show how to
decouple the effect of the style from that of the function by considering
the shapes of the same function but different styles. We also propose a
metric coanalysis approach: if two styles are similar this similarity should
be reflected across different functions.
We show the usability of our methods first on the example of a number of
chess sets which our method helps sort. Next, we investigate the problem
of finding a replacement for a missing tooth given a database of teeth.
