Non-iterative approach for fast and accurate vanishing point detection
JP Tardif - 2009 IEEE 12th International Conference on …, 2009 - ieeexplore.ieee.org
We present an algorithm that quickly and accurately estimates vanishing points in images of

Detecting vanishing points using global image context in a non-manhattan world
We propose a novel method for detecting horizontal vanishing points and the zenith
vanishing point in man-made environments. The dominant trend in existing methods is to …

Deep vanishing point detection: Geometric priors make dataset variations vanish
Deep learning has improved vanishing point detection in images. Yet, deep networks
require expensive annotated datasets trained on costly hardware and do not generalize to …

Vanishing point detection without any a priori information
A Almansa, A Desolneux… - IEEE Transactions on …, 2003 - ieeexplore.ieee.org
Even though vanishing points in digital images result from parallel lines in the 3D scene,
most of the proposed detection algorithms are forced to rely heavily either on additional …
