Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...

background the current distribution of and access to health services along with the future health needs of the population have prompted wide application of geographic information systems (giss). during recent years, gis has been used in public health management for planning and organization of healthcare services. this study investigates geographical accessibility of residential areas in bandar...

objectives: to locate the road emergency stations in fars province based on using spatial multi-criteria decision making (delphi method).    methods: in this study, the criteria affecting the location of road emergency stations have been identified through delphi method and their importance was determined using analytical hierarchical process (ahp). with regard to the importance of the criteria...

A novel definition of the stimulus-specific information is presented, which is particularly useful when the stimuli constitute a continuous and metric set, as, for example, position in space. The approach allows one to build the spatial information distribution of a given neural response. The method is applied to the investigation of putative differences in the coding of position in hippocampus...

Geographic Information Science focuses traditionally on spatial information of geographic scale and associates this per default with outdoor environments. Systems, databases and models are designed for this primary purpose. In this paper, the author discusses the geographic information requirements in indoor environments and, in particular, their differences to ‘outdoor’ geographic information....

DEFINITION Spatial Information Retrieval (SIR) refers to providing access to geo-referenced sources by indexing, searching, retrieving, and browsing [1]. SIR is an interdisciplinary topic involving geospatial information science, data mining, computer network, cognition, and cartography. An example of SIR query could be “Where are the Italian restaurants within 500 meters around a lake park?” F...

Image segmentation is a fundamental step in many of image processing applications. In most cases the image’s pixels are clustered only based on the pixels’ intensity or color information and neither spatial nor neighborhood information of pixels is used in the clustering process. Considering the importance of including spatial information of pixels which improves the quality of image segmentati...

The ornamental and medicinal saffron with high economic value encompasses a great share of non-oil exports in Iran. As a result, identification of suitable areas for saffron cultivation in Ardabil province located in northwestern part of Iran necessitate effective planning for expanding cultivation and production of this product. Given the effect of various environmental factors on growth and y...
