TL;DR: LSD is a linear-time Line Segment Detector giving subpixel accurate results and uses an a contrario validation approach according to Desolneux, Moisan, and Morel’s theory.

TL;DR: A combined line segment and elliptical arc detector, which formally guarantees the control of the number of false positives and requires no parameter tuning, is proposed.

TL;DR: A novel method for automatic vanishing point detection based on primal and dual point alignment detection with the use of the recently introduced PClines dual spaces and a robust point alignment detector leads to a very accurate algorithm.

TL;DR: A comprehensive method for detecting straight line segments in any digital image, accurately controlling both false positive and false negative detections is proposed, based on Helmholtz principle.

TL;DR: This paper addresses the question of identifying the right camera direct or inverse distortion model, permitting a high subpixel precision to fit to real camera distortion, and concluded that, although high degree polynomials were required to reach a high precision of 1/100 pixels, such polynmials were easily estimated and produced a precise distortion modeling without overfitting.
