The present study's main objective is to examine whether problem orientation and problem-solving skills differ according to generalized anxiety disorder (GAD) symptom level or clinical status (seeking help for GAD). Its secondary goal is to examine whether two cognitive variables (intolerance of uncertainty and beliefs about worry) vary according to GAD(More)
An important application of laser range sensing is found in the 3D scanning and modelling of heritage collections, and of sculptures in particular. Since a significant proportion of the statues in the world's museums is composed of marble, the optical properties of this material under laser range sensing need to be understood. Marble's translucency and(More)
Size and scale issues present a complexity problem in visualizing detailed 3D models built from sensor data. A model of Leonardo da Vinci's Mona Lisa, with its thin pictorial layer, illustrates the need for intuitive real-time processing tools that are seamlessly integrated with a multiresolution visualization environment.
— We present an approach to laser range scanning in which quality metrics are used to automatically reduce the number of measurements acquired from a scanner viewpoint. As part of this approach we present improved versions of the orientation and reflectivity quality metrics, as well as introduce two quality metrics: resolvability and planarity. These(More)

Abstract This paper presents a new acquisition method for 3D laser scanners that combines imaging, fast geometrical object tracking, and automatic pose estimation to register range profiles of(More)
This paper presents a new technique for fast, view-dependent, real-time visualization of large multiresolution geometric models with color or texture information. This method uses geomorphing to smoothly interpolate between geometric patches composing a hierarchical level-of-detail structure, and to maintain seamless continuity between neighboring patches(More)
ecently, sensors and algorithms for 3D imaging and modeling of real objects have received significant attention in the computer vision and graphics research fields. The capacity to create, display, and manipulate a high-resolution 3D digital representation of an existing object's shape and appearance can play a significant role in the area of heritage,(More)
