In this paper, we present an algorithm, which automatically generates textured meshes of building facades from a set of multi overlapping calibrated and oriented images. We are in a context of massive data production and aim at high geometric accuracy. The central idea is to create a 3D point cloud. After comparison between object-space and image-space techniques, we choose the latter and compu...

due to the high price of virgin vegetable oils and the drawbacks of the homogeneous catalytic transesterification, in this work an economically profitable alternative process was proposed for biodiesel synthesis in which transesterification of the low-cost waste cooking oil (wco) with methanol in a heterogeneous system was done. alumina impregnated with sodium hydroxide was utilized as a solid ...

–Parallel data processing in cloud has emerged to be one killer application for infrastructure as service to integrate framework for products like portfolio, access these services and deploys the program. Scheduling job process in cloud computing for parallel data processing framework is Nephele. Our analysis presents expected performance of parallel job processing. Nephele is the processing fr...

The need for the processing of surface geometry represents an ubiquitous problem in computer graphics and related disciplines. It arises in numerous important applications such as computer-aided design, reverse engineering, rapid prototyping, medical imaging , cultural heritage acquisition and preservation, video gaming and the movie industry. Existing surface processing techniques predominantl...

In this paper we present an out-of-core editing system for point clouds, which allows selecting and modifying arbitrary parts of a huge point cloud interactively. We can use the selections to segment the point cloud, to delete points, or to render a preview of the model without the points in the selections. Furthermore we allow for inserting points into an already existing point cloud. All oper...
