Record 5 2007-01-31

English

Subject field(s)
  • Remote Sensing
DEF

A technique used in image restoration, enhancement or coding [that is] a separable orthogonal transform or an expansion of the matrix in rank-1 matrices.

CONT

This paper presents a simple and effective method for matching two uncalibrated images. Corner points are firstly extracted as interest points in the two images. Each interest point is assigned one dominant orientation. The initial set of point matches is then obtained by singular value decomposition of a correspondence strength matrix. A new expression of this matrix is introduced to handle more complicated imaging conditions. Each element of this matrix is the similarity measure between two interest points. The new similarity measure is invariant to image rotation by taking into account the dominant orientation of the two interest points. The epipolar geometry constraint is finally imposed to reject the false matches. Experimental results on real images show this approach to be effective for general image matching.

OBS

single value decomposition; SVD: term and abbreviation officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Record 6 2006-11-23

English

Subject field(s)
  • Audiovisual Techniques and Equipment
  • Video Technology
DEF

An electronic device used to perform scaling, usually with a choice of scalings not necessarily an even multiple or fraction of the original scan line or pixel count.

OBS

Scaling refers to conversion of the image matrix without changing the image contents. The digital matrix-oriented projectors and monitors often have a different natural resolution to that of the image signal. The process required to adapt the image from a video signal to a graphics card signal, e. g. 1024 x 768 pixels, is called video scaling.

French

Domaine(s)
  • Audiovisuel (techniques et équipement)
  • Vidéotechnique
DEF

Appareil utilisé pour exécuter la mise à l'échelle d'un support vidéo, avec possibilité de choix de tailles, ce qui modifie généralement le nombre de lignes de balayage et de pixels horizontaux ou verticaux.

OBS

La mise à l'échelle consiste à convertir électroniquement la matrice d'image sans modifier son contenu.

Record 7 2005-04-25

English

Subject field(s)
  • Remote Sensing
OBS

Franklin and McDermid(1993) and Franklin et al.(1996) proposed an alternative technique : a geographic window, where dimensions of a moving kernel are customized and are determined by variogram range. The technique proved to be promising and has been applied to derive texture measures like the co-occurrence matrix for image classification as well as first and second order texture and semivariance moment texture(nugget, range, sill, slope, mean semivariance) for LAI [Leaf Area Index] estimation(Wulder et al. 1997).

OBS

variogram: A geostatic tool used in satellite imagery, especially to put into evidence landscape structures.

OBS

variogram slope: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • slope of the variogram
  • slope of a variogram

French

Domaine(s)
  • Télédétection
CONT

Le variogramme est le plus souvent croissant, c'est-à-dire que les variations radiométriques sont statistiquement plus importantes sur n+1 pixels que sur n pixels. La pente du variogramme est un critère de rugosité : une pente forte caractérise un signal «lisse», sans transitions brutales, tandis qu'une pente faible caractérise un signal «accidenté». Une surface dont le variogramme a une pente constante présente la même texture à toutes les échelles. On dit qu'elle est auto-similaire ou fractale.

OBS

variogramme : Outil de la géostatique servant en imagerie, notamment pour la mise en évidence de structures de paysages.

OBS

pente de variogramme : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).
