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 ...
Photogrammetric refinement of laser-based building roof contours
(2013-08-15)
In this paper a photogrammetric method is proposed for refining 3D building roof contours extracted from airborne laser scanning data. It is assumed that laser-derived planar faces of roofs are potentially accurate, while ...
Historic reconstruction of reservoir topography using contour line interpolation and Structure from Motion photogrammetry
(Taylor & Francis, 2018-09-05)
The geometry of impounded surfaces is a key tool to reservoir storage management and projection. Yet topographic data and bathymetric surveys of average-aged reservoirs may be absent for many regions worldwide. This paper ...
Compensated convexity methods for approximations and interpolations of sampled functions in euclidean spaces: Applications to contour lines, sparse data, and inpainting
(Society for Industrial and Applied Mathematics Publications, 2018-10)
This paper is concerned with applications of the theory of approximation and interpolation based on compensated convex transforms developed in [K. Zhang, E. Crooks, and A. Orlando, SIAM J. Math. Anal., 48 (2016), pp. ...
Unsupervised smooth contour detection
(2016)
An unsupervised method for detecting smooth contours in digital images is proposed. Following
the a contrario approach, the starting point is dening the conditions where contours should not be detected: soft gradient ...
