Coloma Ballester: Multiscale analysis of similarities between images on Riemannian manifolds.

Slides

Our purpose is to compare patches defined on two images. This problem is formulated as the problem of comparing two patches belonging to the same image or to two different images defined on a Riemannian manifold, which can be defined by the image domain with a suitable metric depending on the image. We will define a set of similarity measures that appear as solutions of a degenerate partial differential equation and present some applications of this multiscale analysis of similarities.
