We introduce DID, a pairwise dissimilarity measure applicable to a wide range of data spaces, which leverages the data's internal structure to be invariant to diffeomorphisms.  ...  Measures of similarity (or dissimilarity) are a key ingredient to many machine learning algorithms.  ...  We introduce a dissimilarity called DID (standing for Diffeomorphism Invariant Dissimilarity) which is invariant to smooth diffeomorphisms present between data points.  ...

This geometrical variability is often measured from precisely defined anatomical landmarks such as sulcal lines or meshes of brain structures.  ...  by the dissimilarity measure on currents (Vaillant and Glaunès, 2005; Durrleman et al., 2007) .  ...  By modeling lines as currents, we are able to measure geometrical dissimilarity between curves without assuming point correspondences between objects.  ...
