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

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

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 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

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
