Participants must send the results with a zipped folder to shrec2016@dais.unive.it following the described file format. The deadline for the result submission is February 25th.

Registration to the track is required. Participants can register by sending an email to shrec2016@dais.unive.it.

File format

Resulting correspondences must be submitted in a zipped file containing different ASCII files, one for each shape.

File naming

The correspondence file of a matched shape must have the same name as the shape file (without extension), and ".corr" as extension.

For instance, the correspondence of a shape named "cuts_cat01.off" will be saved in a file named "cuts_cat01.corr".

File content

Each file must be in ASCII format with columns separated by white-spaces and rows separated by a newline character.

Each row of the file corresponds to the match of the relative point of the partial shape (i.e. the match of the $i^{th}$ vertex is contained in the $i^{th}$ row of the result file).

The matched point has to be written following this convention:

  • The first element of the column is the one-based index of the triangle of the canonical pose shape in which the matched point lies.
  • The following three real numbers represent the barycentric weights of the matched point (the weights order must be consistent with the triangle definition on the model file).
  • In case of sparse correspondence, the vertices that have not been matched must have -1 as matched triangle index.
