In this paper, a novel technique combining intensity and range data is presented. Passive (intensity based) and active (range based) techniques used for 3D reconstruction have their limitations and separately, none of these techniques can solve all the problems inherent to the modelling of real environments. Our technique aims to demonstrate how both(More)
OBJECTIVE At a general level, impulsivity is related to both bulimic and general psychopathology. However, it is a complex construct, and the specific role of different forms of impulsivity in psychopathology remains to be determined. The present study of bulimic outpatients examined the association of internally and externally directed impulsive behaviors(More)
This paper presents a process combining range and intensity based techniques, in order to get better 3D models than those obtained using these techniques separately. The procedure needs an initial estimation for internal and external camera parameters for two or more intensity images. The technique uses passive triangulation to refine initial camera(More)
In this paper, we present techniques combining intensity and range data to achieve more realistic three-dimensional models from real world scenes. The principal novelty is the use of the intensity information not only for texturing the final 3D model but also to improve the segmentation of the range data. The technique registers video and range, i.e., the(More)
Insight of patients with schizophrenia seems to be a complex phenomenon that includes elements of a psychological, psychopathological, neurocognitive, and interactional nature. The purpose of this research was to study two of these areas (psychopathology and interpersonal relationships) in order to determine their influence on insight and their(More)
A method for evaluating the change of the referral patterns in consultation-liaison (C-L) psychiatry is described. The method is applied to the study of the 528 requests received by a C-L team for a 2-year period, following the creation of the C-L service. Five types of C-L request are isolated and related to DSM-III-R diagnosis and other clinical(More)
INTRODUCCIÓN Los pacientes con obesidad mórbida que solicitan ser intervenidos quirúrgicamente para perder peso presentan una mayor tasa de trastornos del eje I (depresión mayor, agorafobia, fobia simple, trastorno por estrés postraumáti-co, bulimia nerviosa y trastorno por atracón) y del eje II OBJETIVO: Se ha descrito en los pacientes con obesidad mórbida(More)
