conclusions bscta is easily accessible, less time consuming, and most importantly, a non-invasive technique for detecting intracranial aneurysms. it is also suitable for patients who have been referred to emergency services. therefore, it can be used in emergency conditions and as a first-line diagnostic method in patients with non-traumatic sah. patients and methods sixty consecutive patients ...

Automated generation of digital elevation models (DEMs) from high resolution satellite images (HRSIs) has been an active research topic for many years. However, stereo matching of HRSIs, in particular based on image-space search, is still difficult due to occlusions and building facades within them. Object-space matching schemes, proposed to overcome these problem, often are very time consuming...

Let 3D denote the space of indefinitely differentiable functions of compact carrier on Euclidean space R of dimension p, and denote by 3D' the dual of 3D, that is, 30' is the space of distributions on R; we give 3D and 3D' their usual topologies (see [2]). By 23D, 23D' we denote respectively the spaces corresponding to 3D and 3D' on AXA. Let L be any continuous linear map of 3D—»3D'; then L. Sc...

this paper presents a new three-dimensional curvelet transform based dictionary learning for automatic segmentation of intraretinalcysts, most relevant prognostic biomarker in neovascular age-related macular degeneration, from 3d spectral-domain optical coherencetomography (sd-oct) images. in particular, we focus on the spectralis sd-oct (heidelberg engineering, heidelberg, germany) system, and...

In this paper, we propose a reference model for representing real characters in the 3D virtual space. Most systems have adopted virtual characters into the 3D virtual space to give more realistic situation, where the virtual characters have been controlled by user-steered interfaces. In order to take user immersion, we need to represent real characters into the 3D virtual space. This paper desc...

We present an approach which uses 3D visual landmarks for solving the correspondence problem in Simultaneous Localisation and Mapping (SLAM). The 3D landmarks are computed from camera views of the robot’s local space. Using multiple 2D views, identified landmarks are projected, with their correct location and orientation into 3D world space by scene reconstruction. As the robot moves around the...

In this paper, we suggest a mo indirect 3D object manipulation method information in an augmented reality environm we propose 1) a method that exploits a 2D 3DOF accelerometer, and compass sensors manipulate 3D objects in 3D space, 2) design t to map the control space of mobile phones reality (AR) display space, and 3) confirm the transfer functions by implementation. Our applicable to the desi...
