GrabCut is one of the most powerful semi-automatic segmentation techniques. One main drawback of GrabCut is the need for user interaction in order to initialize the segmentation process. User interaction involves dragging a rectangle around the object of interest in the image to extract it. This restricts GrabCut for binary-label ...

The fundamental matrix (FM) describes the geometric relations that exist between two images of the same scene. Different error criteria are used for estimating FMs from an input set of correspondences. In this paper, the accuracy and efficiency aspects of the different error criteria are studied. We mathematically and experimentally ...

Mobile visualization allows users to visualize data anywhere, anytime, on various mobile clients connected by wireless networks. In this paper, an efficient framework is proposed for the remote rendering of large point-based 3D models represented by QSplats Level-Of-Detail (LOD) on mobile devices. As client-oblivious data model is used, rendering tasks ...

In this article, the wind flow over one of the most important Egyptian historical heritage sites, the Giza Plateau, was investigated using the Computational Fluid Dynamics (CFD) state-of-the-art techniques. The present study addresses the influences of wind flow structure, as an important denudation factor, on the site and its famous ...

Wind influences are important environmental factors that cause deterioration of historical heritage sites. This work presents a computational framework for investigating the influences of the wind flow over such sites. The wind flow is considered to be fully turbulent, isothermal and incompressible. The present framework employs three-dimensional Reynolds Averaged Navier-Stokes ...

This paper presents an integrated system for reconstructing solid models capable of handling large-scale point clouds. The present system is based on new approaches to implicit surface fitting and polygonization. The surface fitting approach uses the Partition of Unity (POU) method associated with the Radial Basis Functions (RBFs) on a ...

The ability to study and understand complex, transient phenomena is critical to the solution of many scientific and engineering problems. A typical time-varying dataset from a computational fluid dynamics (CFD) simulation can contain hundreds of time-steps, and each time-step can have more than millions of data points. Generally, multiple values ...

In this paper, a new hybrid system for 3D objects reconstruction is presented. This system is based on the well-known Ball Pivoting Algorithm (BPA) of Bernardini et al. combined with the Radial Basis Function (RBF) model. The BPA can reconstruct surfaces from very large data sets in a little execution ...
