Multiscale Discrete Geometryof a standard digital straight line by a multi-resolution grid. We then study the multi-resolution of Digital Straight Segments (DSS): we provide a sublinear algorithm computing the exact characteristics of a DSS whenever it is a subset of a known standard line. We finally deduce an algorithm for co

Ellipse Detection with Elemental Subsetse then prove that the global fitting cost can be easily derived from the fitting cost of the samples. Since fitting costs are computed from small samples, the technique can be incorporated in many ellipse detection and recognition algorithms, and in particular, in algorithms that make use of increme

Multi-Label Simple Points Definition for 3D Images Digital Deformable Model deformable partition process. The definition is based on simple intervoxel properties and is easy to implement. A deformation process is carried out with a greedy energy minimization algorithm. A discrete area estimator is used to approach at best standard regularizers classically used in continuou

Marching Triangle Polygonization for Efficient Surface Reconstruction from Its Distance Transformbasic algorithm which produces a complete mesh without any cracks. Our method is useful in the surface reconstruction process of scanned objects. It works over the scalar field distance transform of the object to produce the resulting triangle mesh. First we improve the original algorithm in finding

Topology-Preserving Thinning in 2-D Pseudomanifoldsal images (. images defined on ℤ.) such procedures are usually based on the notion of simple point. By opposition to the case of spaces of higher dimensions (. ℤ., . ≥ 3), it was proved in the 80’s that the exclusive use of simple points in ℤ. was indeed sufficient to develop thinning procedures pro
