“…In a similar vein, [4] and [2] extend barycenter-based classification methods to the SPD Riemannian framework. On the other hand, [9] propose the usage of SPD matrices as a region descriptor in images, with applications in image segmentation. The work in [17] pushed the idea further by allowing the region covariance descriptor to be appended to a deep neural representation of an image, and by doing so introduced the first hints of automatic backpropagation in a Riemannian setting.…”
