NON CONTRASTE [5 records]

Record 1 2006-01-18

English

Subject field(s)
  • Remote Sensing
CONT

Non-linear contrast stretching increases the visibility of areas obscured by shadows and highlights areas of subtle surface differences (eg. ice rises). Histogram equalization highlights areas of subtle surface change.

OBS

non-linear contrast stretching: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • non linear contrast stretching
  • nonlinear contrast stretching

French

Domaine(s)
  • Télédétection
CONT

La méthode d'étirement non linéaire du contraste a un inconvénient important. Chaque valeur dans l'image d'entrée peut avoir plusieurs contrastes de valeurs dans l'image de sortie. [Ainsi,] les objets dans la scène originale perdent leurs valeurs correctes d'intensité relative [...]

OBS

étirement non linéaire de contraste : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Key term(s)
  • étirement non-linéaire du contraste
  • étirement non-linéaire de contraste

Record 2 2005-10-13

English

Subject field(s)
  • Remote Sensing
OBS

Contrast enhancement. Improving the picture by turning up the contrast. Most digital image display systems allow one to break each 'primitive' colour into 256 degrees of intensity. An image that uses this entire intensity scale, that is, that contains values coded from 0 to 255, has excellent contrast, for the colour range will extend from black to white and include fully-saturated colours. In contrast, an image that uses a narrow range of numerical values will lack contrast (it will look 'greyish').

OBS

nonlinear contrast enhancement: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • non-linear contrast enhancement
  • non linear contrast enhancement

French

Domaine(s)
  • Télédétection
CONT

Le rehaussement non linéaire du contraste implique souvent l'égalisation de l'histogramme par un algorithme. La méthode d'étirement non linéaire du contraste a un inconvénient important [:] chaque valeur dans l'image d'entrée peut avoir plusieurs de valeurs dans l'image de sortie.
