A recent convergence of computer graphics and computer vision has produced a set of techniques collectively known as image-based modeling and rendering (IBMR). Image-based modeling refers to the use of images to drive the reconstruction of 3D models. In the case of image-based rendering, the goal is to achieve more realistic and faster renderings and to simplify the modeling task by using image...

Partitioned Global Address Space (PGAS) languages are a popular alternative when building applications to run on large scale parallel machines. Unified Parallel C (UPC) is a well known PGAS language that is available on most high performance computing systems. Good performance of UPC applications is often one important requirement for a system acquisition. This paper presents the memory managem...

The image-based modeling and rendering (IBMR) approaches allow the time complexity of synthesizing novel images to be independent of scene complexity. Unfortunately, illumination control (relighting) is no longer trivial under the image-based framework. To relight the image-based scenery, the scene must be captured under various illumination conditions. This drastically increases the data volum...

This paper presents a novel scheme based on a hybrid NPR/IBMR approach, for providing non-photorealistic virtual environment navigation from images. As a preprocess, we first divide the background and the foreground components in the image and then construct a simple 3D scene model consisting of background model and foreground object models, together with the corresponding nonphotorealistic tex...

School of Information System and Management, National University of Defense Technology, Changsha 410073, China Summary 3D modeling is a key technique to much research and applications. In different fields of research and applications, 3D modeling methods of model-data acquisition and modeling have their own specialties. The paper systemically introduces equipments of 3D data acquisition and mod...

The full plenoptic function describes all of the light passing through some volume of space. This information has at least seven dimensions: a ray of light requires five numbers to locate it (a point in space and a direction), plus wavelength and time. Given a digital representation of the plenoptic function, we can reconstruct arbitrary views of a scene. Unfortunately, adequately sampling the ...

Farmers in the Indus Basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tubewells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater...
