Topologically Correct Image Segmentation Using Alpha Shapes
Abstract. Existing theories on shape digitization impose strong constraints on feasible shapes and require error-free measurements. We use Delaunay triangulation and -shapes to pro...

A 3D Live-Wire Segmentation Method for Volume Images Using Haptic Interaction
Abstract. Designing interactive segmentation methods for digital volume images is difficult, mainly because efficient 3D interaction is much harder to achieve than interaction with...

Minimal Decomposition of a Digital Surface into Digital Plane Segments Is NP-Hard
This paper deals with the complexity of the decomposition of a digital surface into digital plane segments (DPS for short). We prove that the decision problem (does there exist a ...

Exact Euclidean Medial Axis in Higher Resolution
Abstract. The notion of skeleton plays a major role in shape analysis. Some usually desirable characteristics of a skeleton are: sufficient for the reconstruction of the original o...

Duality and Geometry Straightness, Characterization and Envelope
Duality applied to geometrical problems is widely used in many applications in computer vision or computational geometry. A classical example is the Hough Transform to detect linea...

Skeletonization and Distance Transforms of 3D Volumes Using Graphics Hardware
We propose a fast method for computing distance transforms and skeletons of 3D objects using programmable Graphics Processing Units (GPUs). We use an efficient method, called dista...

A New 3D Parallel Thinning Scheme Based on Critical Kernels
Critical kernels constitute a general framework settled in the of abstract complexes for the study of parallel thinning in any dimension. We take advantage of the properties of thi...
