Learning rotation-aware features: From invariant priors to equivariant descriptors
Identifying suitable image features is a central challenge in computer vision, ranging from representations for lowlevel to high-level vision. Due to the difficulty of this task,...

FREAK: Fast Retina Keypoint
A large number of vision applications rely on matching keypoints across images. The last decade featured an arms-race towards faster and more robust keypoints and association algo...

Manifold-based fingerprinting for target identification
In this paper, we propose a fingerprint analysis algorithm based on using product manifolds to create robust signatures for individual targets in motion imagery. The purpose of ta...

Four-dimensional non-linear ray tracing as a visualization tool for gravitational physics
In this paper, general relativistic ray tracing is presented as a tool for gravitational physics. It is shown how standard three-dimensional ray tracing can be extended to allow f...

Panoramic mosaics by manifold projection
As the field of view of a picture is much smaller than our own visual field of view, it is common to paste together several pictures to create a panoramic mosaic having a larger...
