Steerable graph-Laplacian filters for image-valued manifolds MS42

We consider the problem of filtering a set of images lying on a low dimensional manifold, under the assumption that the in-plane rotation of each image is irrelevant. We derive the steerable graph Laplacian on the image-manifold, which accounts for all planar rotations of all images, and show how to use it for image filtering while exploiting all images and their rotations simultaneously. We demonstrate our approach for the denoising of cryo-electron microscopy image datasets.
