Comparing Images Using the Hausdorff Distance

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1993
The Hausdorff distance measures the extent to which each point of a model set lies near some point of an image set and vice versa. Thus, this distance can be used to determine the degree of resemblance between two objects that are superimposed on one ...

Distance from a distance: Psychological distance reduces sensitivity to any further psychological distance.

Journal of Experimental Psychology: General, 2013
What is the difference between far and further? Investigations into such psychological distancing--removal from an egocentric reference point--have suggested similarities between geographical space, time, probability, and social distance. We draw on these similarities to propose that experiencing any kind of distance will reduce sensitivity to any ...

Some distance properties of latent root and vector methods used in multivariate analysis

, 1966
SUMMARY This paper is concerned with the representation of a multivariate sample of size n as points P1, P2, ..., PI in a Euclidean space. The interpretation of the distance A(Pi, Pj) between the ith andjth members of the sample is discussed for some ...

Going the distance: a current view of enhancer action.

Science, 1998
In eukaryotes, transcription of genes by RNA polymerase II yields messenger RNA intermediates from which protein products are synthesized. Transcriptional enhancers are discrete DNA elements that contain specific sequence motifs with which DNA-binding ...

Distance to Nearest Neighbor as a Measure of Spatial Relationships in Populations

, 1954
but since logging operations and the burning and reburning that followed this logging, aspen and white birch have taken over the role as dominants. Thirty-two islands and 5 mainland areas were chosen for the study.

Distance Regularized Level Set Evolution and Its Application to Image Segmentation

IEEE Transactions on Image Processing, 2010
Level set methods have been widely used in image processing and computer vision. In conventional level set formulations, the level set function typically develops irregularities during its evolution, which may cause numerical errors and eventually ...

Distance and proximity [PDF]

Neohelicon, 2010
In order for the value structure of a given culture to be established, a number of its constituents have to be pushed beyond its boundary by shaping an abhorring figure of its Other. The exteriorization of such a figure is a necessary operation of any identity formation.

Long-distance quantum communication with atomic ensembles and linear optics

Nature, 2001
Quantum communication holds promise for absolutely secure transmission of secret messages and the faithful transfer of unknown quantum states. Photonic channels appear to be very attractive for the physical implementation of quantum communication ...

The measurement of distance

Australian Surveyor, 1973
Abstract Radical changes in the technique of distance measurement followed the introduction of long steel ribands, made possible in 1863 by Chesterman's patented process of treating continuous steel strip. Gunter's linked chains, which had been in use for over 250 years, were replaced by steel tapes up to 10 chains in length, with dramatic improvements

Death of distance and the distance puzzle

Economics Letters, 2012
Abstract Despite the onset of globalization, year-by-year cross-country regressions of the gravity model usually suggest that the impediment of geographical distance on bilateral trade is rising, and not declining, over time. This effect of distance is dubbed the distance puzzle.
