$k$-means on Positive Definite Matrices, and an Application to Clustering in Radar Image Sequences

1 code implementation • 8 Aug 2020 • Daniel Fryer, Hien Nguyen, Pascal Castellazzi

We state theoretical properties for $k$-means clustering of Symmetric Positive Definite (SPD) matrices, in a non-Euclidean space, that provides a natural and favourable representation of these data.
