Homoclinic bifurcation near a loop tangent to an invariant straight line

Journal of Differential Equations
This paper is concerned with homoclinic bifurcation of near-Hamiltonian systems. The authors provide a method for studying homoclinic bifurcation by using different order Melnikov functions for a homoclinic loop tangent to an invariant straight line in this system.

Optical/digital invariant recognition of two‐dimensional patterns with straight lines

Optical Engineering, 1996
A novel optodigital pattern recognition method that has shift, rotation, and scale invariant properties is proposed for recognizing 2-D images having straight lines. The proposed method is composed of three stages. In the first stage, the line features of the image are extracted.

Recursive Treatment of Invariance in the System of n Coplanar Straight Lines

The Mathematical Gazette, 1966
(1) Definitions . In the system of n coplanar straight lines each line is produced indefinitely in both directions so that all possible points of intersection (vertices) are obtained.
