Image Compression with Geometrical Wavelets
We introduce a sparse image representation that takes advantage of the geometrical regularity of edges in images. A new class of one-dimensional wavelet orthonormal bases, called ...

Shape Preserving Digitization of Binary Images After Blurring
Topology is a fundamental property of shapes in pictures. Since the input for any image analysis algorithm is a digital image, which does not need to have the same topological char...

A Variational Model for P+XS Image Fusion
We propose an algorithm to increase the resolution of multispectral satellite images knowing the panchromatic image at high resolution and the spectral channels at lower resolutio...

Automatical Adaption of the Stereotactical Coordinate System in Brain MRI Datasets
Abstract: Neuroanatomical and neurofunctional studies are often referenced to a high resolution MR brain dataset. To allow intersubject comparisons of cortical structures, one need...
