Multiple Structure Tracing in 3D Electron Micrographs

Automatic interpretation of Transmission Electron Micrograph (TEM) volumes is central to advancing current understanding of neural circuitry. In the context of TEM image analysis, tracing 3D neuronal structures is a significant problem. This work proposes a new model using the conditional random field (CRF) framework with higher order potentials for tracing multiple neuronal structures in 3D. T...

Two Algorithms for Fast Ray Tracing of Complex Scenes

In this paper we propose two algorithms for fast ray tracing of complex scenes. We test the scene in a pre-processing step with some rays. In this way, we can obtain some information about the coherence of the rays in the scene and about the space coherence among the objects. The pre-processing step allows us of reducing the complexity of the data base of objects. We can build a subset of items...

Edge-tracing algorithm for euclidean voronoi diagram of 3d spheres

Despite of many important applications in various disciplines from sciences and engineering, Voronoi diagram for spheres in a 3-dimensional Euclidean distance has not been studied as much as it deserves. In this paper, we present an edge-tracing algorithm to compute the Euclidean Voronoi diagram of 3-dimensional spheres in O( ) in the worst-case, where is the number of edges of Voronoi diagram ...

Methods for 3D digitization of Cultural Heritage

Complete digital recording of Cultural Heritage is a multidimensional process. It depends highly on the nature of the subject of recording as well as the purpose of its recording. The whole process involves the three-dimensional digitization, digital data processing and storage, archival and management, representation and reproduction. In this paper we briefly review methods for three-dimension...
