Triangulated meshes have become ubiquitous discrete surface representations. In this
paper, we address the problem of how to maintain the manifold properties of a surface while …

Feature matching is a fundamental technique in remote sensing image processing. This
article proposes a new formulation of affine covariant feature matching for remote sensing …

In geometric computer vision, the structure from motion (SfM) problem can be formulated as
a optimization problem with a rank constraint. It is well known that the trace norm of a matrix …

Face frontalization consists of synthesizing a frontally-viewed face from an arbitrarily-viewed
one. The main contribution of this paper is a robust frontalization method that preserves non …

We introduce a new stochastic model incorporating a mixture of uniform and Laplace
distributions. We present basic theoretical properties of this model and discuss related …

In this paper a new completely unsupervised mesh segmentation algorithm is proposed,
which is based on the PCA interpretation of the Laplacian eigenvectors of the mesh and on …

Ordinary least squares estimates can behave badly when outliers are present. An alternative
is to use a robust regression technique that can handle outliers and influential observations …

XML can play several roles in a distributed object system. In particular, data can be
serialized in XML-based formats. XML-encoded data can be more self-describing than data …

This paper focuses on the problem of structure and motion recovery from uncalibrated image
sequences. It has been empirically proven that image measurement uncertainties can be …

The paper focuses on 3D structure and motion factorization from uncalibrated image
sequences. A rank-4 affine factorization algorithm and a robust structure and motion …
