Automatic texture mapping mega projects
Texture mapping of 3D models in fields like architecture and archaeology is a real challenge especially with a large number of images which are not always captured with the ideal photogrammetric order. In this paper, a new algorithm for full automatic texture mapping is developed based on several parameters. The developed algorithm assigns the suitable texture based on the score ... إقراء المزيد

Quantitative quality measure for photorealistic three dimensional models
The demand for virtual photorealistic models has been recently increased especially in the field of documenting large archaeological sites. These models are commonly assessed qualitatively as no quantitative measure tool is available. In this work, a new approach is presented for a quantitative measure of models texture similarity. Deciding for the reference texture is crucial. Metrics that have been used ... إقراء المزيد

Corresponding regions for shadow restoration in satellite high-resolution images
High spatial resolution images available by satellites such as Ikonos, Quickbird, and WorldView-2 provide more information for remote sensing applications, such as object detection, classification, change detection, and object mapping. The presence of shadow reduces the amount of information that can be extracted and consequently makes these applications more difficult or even impossible. In this article, a shadow restoration approach ... إقراء المزيد

Shadow identification in high resolution satellite images in the presence of water regions
Shadow is a main obstacle in features extraction from high resolution satellite images. Water areas provide low reflectance; therefore, they are commonly classified as shadow. In traditional shadow identification procedures, shadow is identified from image histogram in which, water and shadow pixels are mixed. In this study, a new image index is presented. The index histogram separates non-shadow, shadow, and ... إقراء المزيد

Accurate shadow detection from high resolution satellite images
High-resolution satellite images contain a huge amount of information. Shadows in such images generate real problems in classifying and extracting the required information. Although signals recorded in shadow area are weak, it is still possible to recover them. Significant work is already done in shadow detection direction but, classifying shadow pixels from vegetation pixels correctly is still an issue as ... إقراء المزيد

A review on various shadow detection and compensation techniques in remote sensing images
Remote sensing images provide a valuable source of information about the earth’s surface. The presence of shadow can reduce the amount of information that can be extracted from these images. Shadow in remote sensing images is produced due to blockage of a direct light by an object. In spite of the reflectance gathered in the shadow area being weak, there ... إقراء المزيد

Toward an Operating Speed Profile Model for Rural Two-Lane Roads in Egypt
The geometric design, especially the horizontal and vertical alignments, of rural two-lane highway facilities is considered one of the most important factors affecting the quality of traffic service and safety. A consistent highway geometric design is defined to be one that conforms to the driver's expectations. In order to calculate the main measures of design consistency, an accurate operating speed ... إقراء المزيد

The Optimal Method for Classifying High Resolution Satellite Images in EGYPT Environment
The remote sensing society is currently offering a wide variety of digital images that cover most of the Earth’s surface. The up-to-date image data is a promising tool for producing accurate maps. To maximize the benefit of such data, automatic and efficient classification methods are investigated. For the past years, traditional pixel-based classification has been used. Currently, a recent classification ... إقراء المزيد
