Point-set registration methods using the EM algorithm and Softassign that exploits geometric and structural evidence.

The code contains rigid and non-rigid registration algorithms.

The parameters of the methods are especially set to be used with Chui's fish and Chinese character datasets.

Dear Gerard,
the link to the Chui's fish dataset doesn't work anymore, is it possible to provide a working link?

Dear Manon,
you can monitor the status of the process at each iteration by checking the variables vgM (deformed point-set) and Sd (correspondence matrix), inside the main loop of function "match_chui" (or "match_chui_out" if you use the outliers' version).
Also, in case you use this software in your research, I kindly ask you to cite the paper with the same name in the Pattern Recognition Letters journal.
Hope that helps.

Dear Gerard,
After using your non rigid demo, i have two questions:
Is there a function to visualize what is happening? And is it possible to use it for 3D data?
