Traditional research categorizes people’s perceptions towards city into Kevin Lynch’s five elements: node, path, edge, district, and landmark. However, enabled by the proliferation of crowd sourced data this paper utilizes geo-tagged photos to detect, measure, and analyze people’s perceptions. This paper introduces a project called C-IMAGE, which analyzes the interactions between city and human...

Urban branding, as a new approach toward urban development, improves marketing of the city image in different ways by changing the visual image of the city into a brand image. This paper aims to survey the element of urban branding strategies in Iranian cities by examining the criteria of urban branding theory in Iranian cities. The main goal of this investigation is to describe how the cities ...

This paper aims to evaluate what effect applying residents’ urban image to virtual city design (a real time virtual model of an actual city) has on wayfinding performance during ‘flying-based’ navigation mode. Two experiments were conducted to compare two virtual city designs using the virtual model of Tel Aviv city. One design included highlighted urban elements from the residents’ urban image...

In this paper, we propose a city-logging system to collect various types of data around the roads using mobile observation equipment. Since the collected image data from CCTV contains several things which can violate someone’s privacy, we present a secure method to search CCTV image using searchable image encryption system. In addition, we illustrate a city-info service which can be provided by...

The research used the satellite image (Landsat 7 ETM ) within the thermal infrared sixth band (TIR6) and geographic information system (GIS) to determine the air pollution and its relationship with the land cover (LC) and land use (LU) of Baghdad city. Concentration of total suspended particles (TSP), lead (Pb), carbon oxides (CO, CO2), and sulphur dioxide (SO2) were obtained from 22 ground mea...

In this paper, we present an efficient method to synthesize large-scale scenes, such as broad city landscapes. To date, model based approaches have mainly been adopted for this purpose, and some fairly convincing polygon cities have been successfully generated. However, the shapes of real world objects are usually very complicated and it is infeasible to model an entire city realistically. On t...

In existing research about 3D city map, geometrical information of buildings’ facade is derived from video image. In order to improve quality of the geometrical information, range image is used in our research. At first range image of existing buildings is acquired using laser scanners mounted on data acquisition vehicle which runs in the street. After removing obstacles from original range ima...
