Rejection of a deviant point from a straight-line regression
Analytica Chimica Acta, 1985Abstract A statistical procedure is described to help decide whether or not to reject a data point which deviates markedly from a straight-line regression. A Beer's law plot is used to illustrate the procedure.

Fitting straight lines to point patterns
Pattern Recognition, 1984Abstract In many types of point patterns, linear features are of greatest interest. A very general algorithm is presented here which determines non-overlapping clusters of points which have large linearity. Given a set of points, the algorithm successively merges pairs of clusters or of points, encompassing in the merging criterion both contiguity ...

Reasoning with uncertain points, straight lines, and straight line segments in 2D
ISPRS Journal of Photogrammetry and Remote Sensing, 2009Abstract Decisions based on basic geometric entities can only be optimal, if their uncertainty is propagated through the entire reasoning chain. This concerns the construction of new entities from given ones, the testing of geometric relations between geometric entities, and the parameter estimation of geometric entities based on spatial relations ...

What's in a set of points? (straight line fitting)
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1992The problem of fitting a straight line to a planar set of points is reconsidered. A parameter space computational approach capable of fitting one or more lines to a set of points is presented. The suggested algorithm handles errors in both coordinates of the data points, even when the error variances vary between coordinates and among points and can be

The “Best” Straight Line among the Points
American Journal of Physics, 1953The familiar method of fitting a straight line to a set of experimentally observed points by use of least squares, is reviewed, and variations of it briefly discussed. Then methods, apparently not so familiar to many physicists, for estimating the adequacy of the fit thus obtained, and for comparing the results of several such experiments, are ...

Traversing from point-to-point along a straight line with a ballbot
IFAC Proceedings Volumes, 2010Abstract The planar motion to traverse from point to point with a ballbot is discussed. Our aim is to propose an analytical method to plan motions that can be robustly executed by feedback control. The approach is based on defining geometric virtual relations among the generalized coordinates.

On hitting grid points in a convex polygon with straight lines
1991We consider the following problem: Find a set of parallel straight lines with equal spacing to hit all m grid points in a closed region bounded by a convex polygon P with n vertices such that no grid points in a plane fall between two adjacent lines of these parallel lines and size of this set is minimal. We use continued fraction expansions to explore

Optimal Camera Orientation from Points and Straight Lines
2001This paper presents an optimal estimate for the projection matrix for points of a camera from an arbitrary mixture of six or more observed points and straight lines in object space. It gives expressions for determining the corresponding projection matrix for straight lines together with its covariance matrix.
