Extraction and Regularization of Various Building Boundaries with Complex Shapes Utilizing Distribution Characteristics of Airborne LIDAR Points
TL;DR: This study presents an approach for extracting boundaries of various buildings, which have concave boundaries, inner yards, non-right-angled corners, and nonlinear edges, which comprises four steps: building point segmentation, boundary tracing, boundary grouping, and regularization.

A Primitive Comparison for Traffic-Free Path Planning
TL;DR: An in-depth analysis of interpolation curve planners based on continuous curvature Bézier compositions is presented, and a comparison framework to benchmark different path-planning primitives for on-road urban driving is proposed and the evaluation of different primitive configurations and optimization techniques for path- Planning is carried out.

The role of least image dimensions in generalization of object in spatial databases
TL;DR: The paper presents the least admissible dimensions of black lines of spatial object images, according to Saliszczew, adjusted to the needs of database generalization, and secures uniqueness of results on any level of generalization process.

Sub-surface growing and boundary generalization for 3d building reconstruction
Martin Kada,Andreas Wichmann +1 more
TL;DR: In this article, a 3D building reconstruction methodology based on the notion of sub-surface growing as a means for point cloud segmentation of planar surfaces is introduced, where the segmentation process continues below other surfaces, thus allowing stricter rules to help identify and differentiate between the root types of the roof subshapes and their composition to complex roof structures.

Fast classification of handwritten on-line Arabic characters
George Kour,Raid Saabne +1 more
TL;DR: An efficient Arabic handwritten characters recognizer aimed at facilitating real-time handwritten script analysis tasks and achieving fast yet accurate recognition results in a dictionary-free environment is proposed.

Computer representation of planar regions by their skeletons
John L. Pfaltz,Azriel Rosenfeld +1 more
TL;DR: Any region can be regarded as a union of maximal neighborhoods of its points, and can be specified by the centers and radii of these neighborhoods; this set is a sort of "skeleton" of the region.

The Application of Computation and Automatic Drawing Instruments to Structural Generalisation
TL;DR: An account of a series of experiments in computer generalisation, in which the outline of the Netherlands at 1:25 000 scale has been used to generate aseries of generalisations between 1:600 000 and 1:3 500 000.
