Metric rectification for perspective images of planes
David Liebowitz,Andrew Zisserman +1 more
TL;DR: The novel contributions are that in a stratified context the various forms of providing metric information can be represented as circular constraints on the parameters of an affine transformation of the plane, providing a simple and uniform framework for integrating constraints.
Journal ArticleDOI
Creating Architectural Models from Images
TL;DR: Methods for creating 3D graphical models of scenes from a limited numbers of images, i.e. one or two, in situations where no scene co‐ordinate measurements are available are presented.
Proceedings ArticleDOI
Combining scene and auto-calibration constraints
David Liebowitz,Andrew Zisserman +1 more
TL;DR: A simple approach to combining scene and auto-calibration constraints for the calibration of cameras from single views and stereo pairs and examples of various cases of constraint combination and degeneracy as well as computational techniques are presented.
Journal ArticleDOI
Resolving ambiguities in auto–calibration
TL;DR: In this paper, four types of constraints are analyzed for motions with a single direction of the rotation axis, and four different types of constraint are supplemented by known values of the camera's internal parameters or scene constraints in order to resolve ambiguities.
Proceedings ArticleDOI
Simulated fluid flow in feature enhancement
David Liebowitz,Farzin Aghdasi +1 more
TL;DR: In this article, a technique for enhancing certain features in grayscale images is described, which is similar to the watershed algorithm in concept, visualizing the movement of fluid over the image surface to draw conclusions about significant local minima.
