A stable frame rate is important for interactive rendering systems. Image-based modeling and rendering (IBMR) techniques, which model parts of the scene with image sprites, are a promising technique for interactive systems because they allow the sprite to be manipulated instead of the underlying scene geometry. However, with IBMR techniques a frequent problem is an unstable frame rate, because ...

II I hereby certify that this material, which I now submit for assessment on the programme of study leading to the award of Ph.D. is entirely my own work and has not been taken from the work of others save and to the extent that such work has been cited and acknowledged within the text of my work. Abstract While both work with images, computer graphics and computer vision are inverse problems. ...

virtual reality, developing techniques for synthesizing arbitrary views has become an important technical issue. Given an object’s structural model (such as a polygon or volume model), it’s relatively easy to synthesize arbitrary views. Generating a structural model of an object, however, isn’t necessarily easy. For this reason, research has been progressing on a technique called image-based mo...

Abstract: A new technology called “Image-Based Modeling and Rendering (IBMR)” has been attracting much attention in the field of 3-D computer graphics. It aims to describe 3-D spatial data using a set of real images or light rays, while the structure data (shape and texture) is essential for traditional techniques. The authors proposed and developed a real time IBMR system in which all the proc...

We present a new rendering technique, termed LOD-sprite rendering, which uses a combination of a level-of-detail (LOD) representation of the scene together with reusing image sprites (previously rendered images). Our primary application is an acceleration technique for virtual environment navigation. The LOD-sprite technique renders an initial frame using a full-resolution model of the scene ge...

The growing complexity of hardware optimizations employed by multiprocessors leads to subtle distinctions among allowed and disallowed behaviors, posing challenges in specifying their memory models formally and accurately, and in understanding and analyzing the behavior of concurrent software. This complexity is particularly evident in the IBM® Power Architecture® , for which a faithful specifi...

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 tube-wells. these wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwate...
