Influence of the boundary conditions on the result of non-linear image registration
The focus of many non-parametric image registration algorithms lies on the solution of non-linear partial differential equations. We offer a simple solution procedure therefor bas...

3D Model Retrieval Based on 3D Discrete Cosine Transform
: The content-based retrieval systems for 3D models on the Web become necessary since digital databases of 3D objects are growing. In this paper, we propose a new method to describ...

Perturb-and-MAP Random Fields: Using Discrete Optimization\\to Learn and Sample from Energy Models
We propose a novel way to induce a random field from an energy function on discrete labels. It amounts to locally injecting noise to the energy potentials, followed by finding t...

Discretization of the Radon transform and of its inverse by spline convolutions
Abstract--We present an explicit formula for B-spline convolution kernels; these are defined as the convolution of several B-splines of variable widths and degrees . We apply our r...
