✴ Characterization of the Probabilistic Volumetric Models (PVM) as a new representation for 3-d scene understanding. ✴ The first evaluation of the performance of several local shape descrip-tors extracted from the PVM in terms of accuracy for object classification. ✴ Histogram-based descriptors are of particular interest as they are the most popular and(More)
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) comorbid with oppositional defiant disorder (ODD) or conduct disorder (CD) and substance abuse/dependence seems to represent a specific subset within the phenotypic ADHD spectrum. METHODS We applied complex segregation and linkage analyses in a set of multigenerational families densely segregating(More)
—This paper presents a novel framework for surface reconstruction from multi-view aerial imagery of large scale urban scenes, which combines probabilistic volumetric modeling with smooth signed distance surface estimation, to produce very detailed and accurate surfaces. Using a continuous probabilistic volumetric model which allows for explicit(More)

A new representation of 3-d object appearance from video sequences has been developed over the past several which combines the ideas of background modeling and volumetric multi-view reconstruction. In this representation, Gaussian mixture models for intensity or color are stored in volumetric units. This 3-d probabilistic volume model, PVM, is learned from(More)
This paper presents a method that combines Benders decomposition and column generation to solve the multi-activity tour scheduling problem. The Benders decomposition approach iterates between a master problem that links daily shifts with tour patterns and a set of daily subproblems that assign work activities and breaks to the shifts. Due to its structure,(More)
