The research is aim to create MRT: Metropolitan Rapid Transit Authority of Thailand (Underground Train) and BTS: Bangkok Mass Transit System Public Company Limited (Sky Train) interactive route navigation map. This map shows the whole routes of both MRT and BTS train stations which are located in the interactive manner. The design is not only a proposal for showing the whole information about d...

Underground coal fires can increase surface temperature, cause cracks and collapse, release poisonous harmful gases, which significantly harm the ecological environment humans. Traditional methods of extracting fires, such as global threshold, K-mean active contour model, usually produce many false alarms. Therefore, this paper proposes an improved model by introducing distinguishing energies o...

This paper attempts at authenticating users in the hardened password mechanism, through the use of contour mapping techniques. Students of the computer science department at the University of Mauritius have been dealing with contour mapping techniques in computer graphics and password mechanisms during their final year. This work aims at introducing them to the development of simple components ...

Contour maps provide a general method for recognizing twodimensional shapes. All but blank images give rise to such maps, and people are good at recognizing objects and shapes from them. The maps are encoded easily in long feature vectors that are suitable for recognition by an associative memory. These properties of contour maps suggest a role for them in early visual perception. The prevalenc...

during an 11 days mission in february 2000 the shuttle radar topography mission (srtm) collected data over 80% of the earth's land surface, for all areas between 60 degrees n and 56 degrees s latitude. since srtm data became available, many studies utilized them for application in topography and morphometric landscape analysis. exploiting srtm data for recognition and extraction of topographic ...

Self Organizing Maps (SOMs) have attracted the attention of many computer vision scientists, particularly when dealing with image segmentation as a contour extraction problem. The idea of utilizing the prototypes (weights) of a SOM to model an evolving contour has produced a new class of Active Contour Models (ACM s), known as SOM based ACM s. Such models have been proposed in general with the ...

This pqm pments a rasterbased algorithm for reconstruction of 3-D terrain data from contour information appearing on the conventional 2-D map The height of an interior point between two neighboring contam is defined by a linear interpolation formula wt.lose variables are the height of those contours arid distance from the point to the contours. The distance from an interior mint to the contour ...

The issue of graphic map load is currently very often overlooked. Conversely, having an objective knowledge the level a helps cartographers to assume map’s readability and suitability for target group users. aim this study is, therefore, use Graphic Map Load Measuring Tool (GMLMT) Subband Entropy script as metrics evaluate influence terrain type (plains, hills, highlands, mountains, high mounta...

A subtask of voice conversion is to accurately map the pitch contour of a source speaker to a target speaker. So far, the most widely employed method for carrying out this mapping is based on adjusting the pitch range of the source speaker to match the target while keeping the shape of the contour unchanged. In this project, we investigate four alternative algorithms for pitch contour mapping a...
