This paper addresses the challenge of automatic annotation of images for semantic image retrieval. In this research, we aim to identify visual features that are suitable for semantic annotation tasks. We propose an image classification system that combines MPEG-7 visual descriptors and support vector machines. The system is applied to annotate cityscape and landscape images. For this task, our ...

Characterizing the effects of landscape features on genetic variation is essential for understanding how landscapes shape patterns of gene flow and spatial genetic structure of populations. Most landscape genetics studies have focused on patterns of gene flow at a regional scale. However, the genetic structure of populations at a local scale may be influenced by a unique suite of landscape vari...

This paper will concentrate on the result of a research based on comparative study between two Persian gardens in different micro climates in arid regions. Sustainability could be observed in many aspects and elements of traditional Iranian architecture and landscape architecture, and this method of design has used to solve many problems for many centuries. Gardens of Iran have had special role...

Understanding the environmental factors influencing animal movements is fundamental to theoretical and applied research in the field of movement ecology. Studies relating fine-scale movement paths to spatiotemporally structured landscape data, such as vegetation productivity or human activity, are particularly lacking despite the obvious importance of such information to understanding drivers o...

Moving from the exact result that drainage network configurations minimizing total energy dissipation are stationary solutions of the general equation describing landscape evolution, we review the static properties and the dynamic origins of the scale-invariant structure of optimal river patterns. Optimal channel networks (OCNs) are feasible optimal configurations of a spanning network mimickin...

The erosive action of rivers and seas has immense influence on the appearance of the physical landscape. However, the creation of several important river and coastal features are not available in terrain creation software and systems. We have designed algorithms to easily create these features, namely (1) river meanders, (2) river deltas, (3) coastal cliffs, and (4) beaches. A terrain that does...

The coastal landscape is relatively new and complex category that offers the potential of sharing the sciences of architecture, perspective, nature and the environment, tourism and hospitality, beyond their physical effects on one another, their widespread effects in enhancing identity and the quality of the architectural atmosphere cannot be ignored. Approaches to greeting with beaches in Isla...

landscape metrics quantifies structural features of the landscape. one of the advantages of these metrics is a possibility to use them in fast cumulative assessment of the development activities in the environment. in this paper, the cumulative effects of road network expansion on the tree cover of gorgan, kordkuy, aliabad townships in golestan province were investigated. to prepare the require...
