Coarse-level object recognition using interlevel products of complex wavelets
This paper introduces the Interlevel Product (ILP) which is a transform based upon the Dual-Tree Complex Wavelet. Coefficients of the ILP have complex values whose magnitudes indi...

Geodesic Image Matching: A Wavelet Based Energy Minimization Scheme
In this paper, we first detail the geodesic matching of images which consists in minimizing an energy resulting from a Riemannian metric on a manifold of images, which itself come...
