Synchronisation of partial multi-matchings via non-negative factorisations

作者:

Highlights:

• Partial permutation synchronisation is relevant for multi-matching problems.

• We derive an improved algorithm based on non-negative factorisations.

• A novel initialisation procedure for the non-convex problem is presented.

• We introduce a new projection approach to obtain a binary solution.

• The approach achieves superior results that are guaranteed to be cycle-consistent.
