We present a class of region growing algorithms based on an analogy to a mass suspended in a eld of forces. The mass represents the growing region, and the eld represents the degree of concordance between local pixel values and the color characteristics of the region. The algorithms are particularly well suited to systems that are looking for speciic simply-connected shapes in local areas of in...

In a context of globalization, municipalities and metropolitan regions are involved in international competition to support economic growth. This leads to new forms of collaboration between public authorities and businesses, giving birth to new forms of urban and metropolitan governances. Moreover, many old neighborhoods of the central city and some districts of the old suburbs face growth in u...

An algorithm from Radon transform to obtain local tomography from multiple CT slices for localized 3D reconstruction is developed. The proposed method uses Radon transform to obtain projections for a region of interest. Reconstructing a particular cross section of a human body using local data will significantly reduce Xray exposure during imaging. Image reconstruction is performed using filter...

In this paper, we propose and analyze the design notion of dual-region mobility management (DrMoM) for achieving scalable, efficient location management of mobile nodes in ad hoc networks. The basic idea is to employ local regions to complement existing home region based location service schemes that assign a home region through hashing to a mobile node and have mobile nodes in both the home an...

This report provides additional results on local region statistics and accompanies the work in [2]. In particular, we derive the Euler-Lagrange equations of the local Gaussian region model including variance as well as the local nonparametric model. Moreover, we show some experimental results on contour tracking with local region statistics. 1 Euler-Lagrange Equations for Local Region Statistic...

Local region conservation has been observed in recent years and become more and more important in structure biology. Recent researches point out that local conservation regions are correlated to protein functional sites and functions and studies show that some local conservation on sequence or structure are close to binding area. Hence, in order to realize how function works, we can discover lo...

today, the tourism industry is a major source of income for many countries. but the tourism as an economic activity mentioned before, is a cultural phenomenon in nature and the main attraction of tourism development as well. given the special vulnerability and fragility of cultural heritage, tourism development, in some cases, can cause damage to indigenous cultural patterns. this is in relatio...

SWOT analysis is used extensively as an assessment and planning method, particularly in tourism planning. However, there are little documentations on application of SWOT analysis in ecotourism. An assessment on systematic use of SWOT analysis was carried out in the present study to highlight the applicability of the SWOT technique in detailed investigations. In this study, based on field survey...
