Resection of brain tumors is a tricky task in surgery due to its direct influence on the patients'
survival rate. Determining the tumor resection extent for its complete information via-à-vis …

Despite considerable efforts, description of molecular shape is still largely an unresolved
problem. Given the importance of molecular shape in the description of spatial interactions …

This paper presents new topological and geometric properties of Gauss digitizations of
Euclidean shapes, most of them holding in arbitrary dimension d. We focus on r-regular …

Accurate camera calibration is a well-known and widely used task in computer vision that
has been researched for decades. However, the standard approach based on checkerboard …

Local image features are routinely used in state-of-the-art methods to solve many computer
vision problems like image retrieval, classification, or 3D registration. As the applications …

Depending on the application, local feature detectors should comply with properties that are
often contradictory, eg distinctiveness vs. robustness. Providing a good balance is a …

In many applications of geometric processing, the border of a continuous shape and of its
digitization (ie, its pixelated representation) should be matched. Assuming that the …

This article focuses on the classical problem of the control of information loss during the
digitization step. The properties proposed in the literature rely on smoothness hypotheses …
