Breast Cancer is a disease that is prevalent in many countries. Computer-Aided detection (CAD) systems have been developed to assist radiologists in detecting breast cancer. This paper discusses an algorithm for architectural distortion (AD) detection with a better sensitivity than the current CAD systems. 19 images containing ADs were preprocessed with a median filter and Gabor filters to extr...

Voluminous CAD models are produced in industry and architecture to design complex mechanical and architectural structures. The use of these models to set up virtual worlds is a rather tedious and laborious work. To simplify this task, we have combined a series of tools which help us to build in a rapid and e cient way virtual world experiments from complex CAD models. These tools perform variou...

We present a novel approach for optimizing acoustic parameters using sensitivity analysis for computer-aided design and analysis of architectural models. Our approach builds on recent low-dispersion wave-based acoustic solvers that can accurately compute the pressure field in large models. We present an efficient technique to compute the gradient of the pressure field using automatic differenti...

The use of terrestrial laser scanners in architectural survey applications has become more and more common. Row data complexity, as given by scanner restitution, leads to several problems about design and 3D-modelling starting from Point Clouds. In this context we present a study on architectural sections and mathematical algorithms for their shape reconstruction, according to known or definite...

Accurate calculation of direct solar radiation with current methods is slow and frequently requires oversimplification of building geometry to obtain expedient performance simulations. This paper describes the use of a fast new method for calculating direct solar gains on architectural CAD models at any stage in design. A pre-processing module computes direct incident solar radiation with high ...

Soft computing techniques are gaining momentum as tools for network traffic modeling, analysis and control. Efficient hardware implementations of these techniques that can achieve real-time operation in high-speed communications equipment is however an open problem. This paper describes a platform for the development of fuzzy systems with applications to communications systems, namely network t...

In the Architectural-Engineering-Construction & Facility Management industry, project progress tracking is an important management task. Currently, this task still requires a significant amount of non value-adding manual effort that interferes with value-adding work. Additionally, current practice may lead to approximate or unreliable results. In this paper, the authors present an approach fusi...

The paper describes a new approach for the generation of architectural orthoimages using digital surface models, based on a CAD model of the object. The model is supposed to consist of surface elements, plane or curved. All surface elements of the CAD model are orthogonally projected onto the reference plane. For each grid element the elevation above or below the reference plane are calculated ...

DISTORTIONS Mehul Sampat, Mia Markey, Alan Bovik The University of Texas at Austin e-mail: [email protected] Screening mammography, x-ray imaging of the breast, is currently the most effective tool for early detection of breast cancer. However mammography is not perfect. Detection of suspicious abnormalities is a repetitive, fatiguing and extremely difficult task for radiologists. A number ...

Widely used for architectural design, CAD systems such as AutoCAD, provide powerful modeling functionalities. However, they are often too complex for an architect to use, especially during the conceptual design stage involving primarily sketching of ideas. Also, interactions are typically driven by mouse and keyboard, but these devices cannot be used as freely as a pencil. For an architect, a t...
