adaptation of the lord of the rings is considered by many to be among the greatest, most successful and at the same time most popular of the above mentioned trend so far. it is my intention to look at the success and popularity of this epic fantasy in the light of the 9/11 attacks and the war on terror context of g. w. bush’s aura. in so doing i aim at bringing into the light the determining fa...
High-resolution stereo satellite imagery is widely used in environmental monitoring, topographic mapping, and urban three-dimensional (3D) reconstruction. However, a critical issue in these applications using high-resolution stereo satellite imagery is to improve the accuracy of point geo-positioning. This paper presents a framework for comparison of the performance of the three-dimensional (3D...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
today, persian poetry is of great importance to many scholars around the world. the interest and attention of various cultures toward such a fine literature has given quite a good motivation for a comparative study. the major concern of the study is to investigate how nature is depicted through the works of the great english poet, william wordsworth (1770-1850) and the outstanding contemporary ...
The search of corresponding points in between images of the same scene is a well known problem in many computer vision applications. In particular most structure from motion techniques depend heavily on the correct estimation of corresponding image points. Most commonly used approaches make neither assumptions about the 3D scene nor about the relative positions of the cameras and model both as ...
3D point cloud registration is fragile to outliers, which are labeled as the points without corresponding points. To handle this problem, a widely adopted strategy estimate relative pose based only on some accurate correspondences, achieved by building correspondences identified inliers or selecting reliable ones. However, these approaches usually complicated and time-consuming. By contrast, vi...
The ability to generate accurate and detailed three-dimensional (3D) maps of a scene from a mobile platform is an essential technology for a wide variety of applications from robotic navigation to geological surveying. In many instances, the best vantage point is from above, and as a result, there is a growing demand for low-altitude mapping solutions from micro aerial vehicles such as small qu...
Modern plant phenotyping requires tools that are robust to noise and missing data, while being able efficiently process large numbers of plants. Here, we studied the skeletonization architectures from 3D point clouds, which is critical for many downstream tasks, including analyses shape, morphology, branching angles. Specifically, developed an algorithm improve at branch points (forks) by lever...
this article is intended to provide an overview of various aspects of clinical pet/ct. these include discussions of: (i) important areas of clinical application; (ii) opportunities in clinical research; (iii) scanner and operating-mode considerations (e.g. bgo vs. lso, lyso or gso scanners, 2d vs. 3d imaging). (iv) study-specific considerations (e.g. patient preparation and positioning issues, ...
