Computer-Assisted Assembling of Fragmented Objects

described system provides the user with enough degrees of freedom to exploit his experience and
intuition (as an art historian or a restorer) in an interactive manner. Once the user has defined some
constraints, the system searches for a suitable solution, using a global energy minimization that
simultaneously considers all the pieces involved in the reconstruction process. Additionally, our
framework provides the possibility to work with the pieces in a hierarchical way, mimicking the
traditional physical procedure that archeologists use to reassemble tangible fractured objects. The
frameworks is designed to work even with fragments that could have been severely damaged or
eroded. On those datasets, automatic approaches may often fail, since the fractured regions do not
contain enough geometric information to infer the correct matches.
We present some successful uses of our framework on real application scenarios.
