GA for straight-line grid drawings of maximal planar graphs

Egyptian Informatics Journal, 2012
A straight-line grid drawing of a planar graph G of n vertices is a drawing of G on an integer grid such that each vertex is drawn as a grid point and each edge is drawn as a straight-line segment without edge crossings.

AUTOMATIC GLOBAL REGISTRATION BETWEEN AIRBORNE LIDAR DATA AND REMOTE SENSING IMAGE BASED ON STRAIGHT LINE FEATURES [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
An automatic global registration approach for point clouds and remote sensing image based on straight line features is proposed which is insensitive to rotational and scale transformation. First, the building ridge lines and contour lines in point clouds

INFLUENCE OF DIFFERENT LIVING HINGES GEOMETRIES TO COMPLIANT STRAIGHT LINE MECHANISM TRAJECTORY

Journal of Industrial Design and Engineering Graphics
Classical straight-line mechanisms are one of the most interesting, both from a theoretical and practical point of view. In many cases, those mechanisms frequently produce a nearly straight trajectory rather than one perfectly straight.

Zebra-crossing detection based on cascaded Hough transform principle and vanishing point characteristics

Open Computer Science, 2023
In this study, a zebra-crossing detection method based on cascaded Hough transform (CHT) and vanishing point (VP) characteristics is proposed. In this method, the principle of detecting straight lines in the parallel coordinate system is applied to zebra-

Pencils of circles with a straight line and circle as the basic elements

Дифференциальная геометрия многообразий фигур, 2019
Pencils of circles with are a straight line and a circle as the basic ele­ments are investigated. Three cases of arrangement of a basic straight line and a circle are considered: when the straight line does not intersect a circle, when the straight line ...
