We describe a procedure for reconstructing documents that have been shredded by hand, a problem that often arises in
forensics. The proposed method first applies a polygonal approximation in order to reduce the complexity of the boundaries and
then extracts relevant features of the polygon to carry out the local reconstruction. In this way, the overall complexity can be
dramatically reduced because few features are used to perform the matching. The ambiguities resulting from the local
reconstruction are resolved and the pieces are merged together as we search for a global solution. The preliminary results
reported in this paper, which take into account a limited amount of shredded pieces (10–15) demonstrate that feature-matchingbased
procedure produces interesting results for the problem of document reconstruction.
