Code that implements the NmfSync method for the synchronisation of partial permutation matrices, as described in [1]. When you use this code, you are required to cite [1]. [1] Synchronisation of Partial Multi-Matchings via Non-negative Factorisations F. Bernard, J. Thunberg, J. Goncalves, C. Theobalt. Pattern Recognition. 2019 Please refer to demo_nmfsync.m for an example how to use this code. Note: a custom version of Matlab's nnmf() function for nonegative matrix factorisation method has been used to obtain better memory efficiency. Due to license issues this file cannot be provided.
