Photogrammetric refinement of LiDAR-derived building roof contours
(Taylor & Francis Ltd, 2018-01-01)
In this paper, a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne Light Detection And Ranging (LiDAR) data. It is assumed that LiDAR-derived planar faces of roofs are ...
Rectilinear building roof contour extraction based on snakes and dynamic programming
(2013-01-01)
This paper presents a method for extracting building roof contours from digital images collected over urban landscapes. The proposed method utilizes an energy function based on snakes that represents building roof contours ...

Extraction of building roof contours from the integration of high-resolution aerial imagery and laser data using Markov random fields
(Taylor & Francis Ltd, 2018-01-01)
This study proposes a method for the automatic extraction of building roof contours from the integration of airborne laser scanning (ALS) and photogrammetric data using the Markov random field probabilistic approach. ...

Extração automática de contornos de telhados usando dados de varredura a laser e campos randômicos de Markov
(Universidade Federal do Paraná (UFPR), Centro Politecnico, 2008-01-01)
This paper proposes a methodology for automatic extraction of building roof contours from a Digital Elevation Model (DEM), which is generated through the regularization of an available laser point cloud. The methodology ...
Automatic Identification and Extraction of Pectoral Muscle in Digital Mammography
(Springer, 2019-01-01)
Mammography is a worldwide image modality used to diagnose breast cancer and can be used to measure breast density (BD). In clinical routine, radiologist perform image evaluations through BIRADS assessment. However, this ...
