Texture mapping is a common operation to increase the realism of three-dimensional meshes at low cost. We propose a new texture optimization algorithm based on the reduction of the physical space allotted to the texture image. Our algorithm optimizes the use of texture space by computing a warping function for the image and new texture coordinates. Neither the mesh geometry nor its connectivity...

Maps of forest biomass are important tools for managing natural resources and reporting terrestrial carbon stocks. Using the San Juan National Forest in Southwest Colorado as a case study, we evaluate regional biomass maps created using physical variables, spectral vegetation indices, and image textural analysis on Landsat TM imagery. We investigate eight gray level co-occurrence matrix based t...

BACKGROUND Regular physical examination contributes to early detection and timely treatment, which is helpful in promoting healthy behaviors and preventing diseases. The objective of this study is to compare the annual physical examination (APE) use between rural and urban elderly in China. METHODS A total of 3,922 participants (60+) were randomly selected from three urban districts and three...

The growth of urban populations in recent decades requires physical elements such as residential, commercial and cultural spaces and the development of infrastructure such as streets and highways, which will open a new horizon to the historic texture of cities and how to preserve and restore them. The development of new urban textures along with the lack of attention to the historic texture and...

Rural areas, where 47.6% of the Croatian population lives are not generally the focus of research; yet there are challenges which affect the rural population that often go unreported. These communities often exhibit disadvantages in many areas of health. The aim of this study is to examine the specific health needs and related determinants of rural populations influenced by transition that were...

extended abstract 1. introduction spatial expression of increase in earth planet population as the consequence of industrialization, improving the living standards, and reducing the amount of epidemic diseases in the past century, has been the physical-spatial development of urban and rural settlements. this transformation, especially during past decade, beside the technological advances, has s...

BACKGROUND Although physical activity is recognised to be an important determinant of health and nutritional status, few instruments have been developed to assess physical activity in developing countries. The aim of this study was to compare the validity of the short form of the International Physical Activity Questionnaire (IPAQ) and a locally adapted version of the Physical Activity Question...

BACKGROUND Despite the health risks, physical inactivity is common. Identifying the correlates of physical activity to inform the design of interventions to reduce the disease burden associated with physical inactivity is a public health imperative. Rural adults have a unique set of characteristics influencing their activity behaviour, and are typically understudied, especially in England. The ...
