The potential role that rectification of ENSO plays as a viable mechanism to generate climate anomalies on the decadal and longer time scales demands a thorough study of this process. In this paper, rectification of ENSOwas studied using an ocean GCM that has a realistic seasonal cycle. In addition to conducting a pair of forced ocean GCM experiments with and without ENSO fluctuations, as done ...

A central theme throughout Thomas Pogge’s path-breaking World Poverty and Human Rights is that the global political and economic order harms people in developing countries, and that our duty toward the global poor is therefore not to assist them, but to rectify injustice. But does the global order harm the poor? I argue elsewhere that there is a sense in which this is indeed so, at least if a c...

We describe an important element of an automatic sport analysis system. This element continuously estimates the image-to-model homography from the video stream of a single camera. Here, we focus on the incremental image-to-image updating of the homography matrix, which greatly facilitates real-time operation. This updating relies on the automatic tracking of interest lines and points and on the...

Inversion of the perspective mapping in acquired images enables an autonomous vehicle to perform vision-based navigation tasks, such as obstacle detection. We present work on affine rectification that restores the parallel property of a traffic lane, using the vanishing point of equally spaced parallel lane boundaries. Experimental results demonstrate the potential of our new algorithm.

This work deals with the recovery of illusory linear clues from perspectively skewed documents with the purpose of using them for rectification. The computational approach proposed implements the perceptual organization principles implicitly used in textual layouts. The numerous examples provided show that the method is robust and viewpoint and scale invariant.

Orthophotomaps obtained from satellite images are one of the basic products used by geousers. The paper describes in detail the whole process of orthorectification and triangulation of satellite images from Cartosat. The impact of the number and distribution of GCPs on the results of triangulation is presented. The paper includes the values of orthorectification accuracy obtained for various DE...

We address the problem of 3-D reconstruction from a single perspective view of a mirror symmetric scene. We establish the fundamental result that it is geometrically equivalent to observing the scene with two cameras, the cameras being symmetrical with respect to the unknown 3-D symmetry plane. All traditional tools of classical 2-view stereo can then be applied, and the concepts of fundamental...

MAXIMUM LIKELIHOOD ESTIMATOR OF Drops out of computation of likelihood ratio. DISTRIBUTION OF CONSTRAINT Under normal errors the Euclidean inner product turns out to be practically normal with variance: CONSTRAINTS Five or more orthogonality relations in the form of the Euclidean inner product determine the absolute conic. Rectifying transformation is obtained by Cholesky decomposition. Active ...

We investigate possible causes of molecular rectification in electrode−molecule− electrode junctions. By using a simple model and simulated conductance histograms, we show that a molecular bias drop is responsible for rectification; conversely, asymmetric molecule−electrode couplings do not directly result in rectification. Instead, the degree of coupling (a)symmetry can be observed in the line...
