Shadow detection improvement using spectral indices and morphological operators in Urban Areas in high resolution images
(2015-01-01)
While high-resolution remote sensing images have increased application possibilities for urban studies, the large number of shadow areas has created challenges to processing and extracting information from these images. ...
Ghosts of transparency — shadows cast and shadows cast out
Code. Protocol. Channel. Data. Information. In everyday conversations,
these words do not evoke images of buildings or of cities. And yet they
have entered the common parlance of an architecture and urbanism
looking to ...
DESHADOWING OF HIGH SPATIAL RESOLUTION IMAGERY APPLIED TO URBAN AREA DETECTION
(Univ Federal Parana, Centro Politecnico, 2019-01-01)
Different built-up structures usually lead to large regions covered by shadows, causing partial or total loss of information present in urban environments. In order to mitigate the presence of shadows while improving the ...
Predição de sombras de edifícios sobre vias urbanas com base em modelos digitais de elevações e dados de imagens aéreas de alta resolução
(Universidade Federal do Paraná (UFPR), Centro Politecnico, 2008-01-01)
This research presents a methodology for prediction of building shadows cast on urban roads existing on high-resolution aerial imagery. Shadow elements can be used in the modeling of contextual information, whose use has ...

Morfologia matemática aplicada à detecção de sombras e nuvens em imagens de alta resolução
(2008-04-01)
The spatial resolution improvement of orbital sensors has broadened considerably the applicability of their images in solving urban areas problems. But as the spatial resolution improves, the shadows become even a more ...
Método monoscópico para a determinação automática da altura de edifícios em fotografias aéreas
(Universidade Federal do Paraná (UFPR), Centro Politecnico, 2008-01-01)
This paper proposes a monoscopic method for automatic determination of building's heights in digital photographs areas, based on radial displacement of points in the plan image and geometry at the time the photo is obtained. ...
