in other parts of the hippocampal formation (see below), Department of Physiology but here the term “place cell” is reserved for the principal SUNY cells of CA3 and CA1. Health Sciences Center at Brooklyn Functionally, place cells are characterized by locaBrooklyn, New York 11203 tion-specific firing. A given place cell is intensely active only when the rat’s head is in a certain part of the envi-

The study involves segmentation of the image using the three segmentation modules of three software namely ERDAS Imagine, ENVI and eCognition to extract building features. The best parameters for segmenting buildings have been established. New method of evaluation has been presented for evaluating segmentation quality. The results of three segmentation modules are assessed using the proposed ev...

The identification of materials by measuring and analyzing their reflectance spectra has been an important method used in analytical chemistry for decades. Now, airborne and space-based imaging spectrometers give scientists the opportunity to detect materials and map their distributions across the landscape. With new satelliteborne sensor planned for the future, for example HYSPIRI (HYPerspectr...

The goal of this study was to map and quantify the number of newly constructed buildings in Accra, Ghana between 2002 and 2010 based on high spatial resolution satellite image data. Two semi-automated feature detection approaches for detecting and mapping newly constructed buildings based on QuickBird very high spatial resolution satellite imagery were analyzed: (1) post-classification comparis...

The goal of this research is to find the most suitable computer simulation software for assessment of urban design performance from physical point of view. Although there are many physical simulation tools available today, there is no one which covers all the needs of urban design. After initial research of available software, we have chosen to assess three applications: ENVI-met, Project Vasar...

Georeferencing images is a laborious process so schemes for automating this process have been under investigation for some time. Among the most promising automatic registration algorithms are those based on the fast Fourier transform (FFT). The displacement between two given images can be determined by computing the ratio F1 conjðF2Þ=jF1F2j; and then applying the inverse Fourier transform. The ...
