L'étirement d'histogramme (aussi appelé "linéarisation d'histogramme" ou "expansion de la dynamique") consiste à répartir les fréquences d'apparition des pixels sur la largeur de l'histogramme. Ainsi, il s'agit d'une opération consistant à modifier l'histogramme de telle manière à répartir au mieux les intensités sur l'échelle des valeurs disponibles. Ceci revient à étendre l'histogramme afin que la valeur d'intensité la plus faible soit à zéro et que la plus haute soit à la valeur maximale. De cette façon, si les valeurs de l'histogramme sont très proches les unes des autres, l'étirement va permettre de fournir une meilleure répartition afin de rendre les pixels clairs encore plus clairs et les pixels foncés proches du noir. 4, record 4, French, - %C3%A9talement%20d%27histogramme

Linear contrast enhancement... linearly expands the original digital values of the remotely sensed data into a new distribution. By expanding the original input values of the image, the total range of sensitivity of the display device can be utilized. Linear contrast enhancement also makes subtle variations within the data more obvious. These types of enhancements are best applied to remotely sensed images with Gaussian or near-Gaussian histograms, meaning, all the brightness values fall within a narrow range of the histogram and only one mode is apparent. There are three methods of linear contrast enhancement : Minimum-Maximam Linear Contrast Stretch [;] Percentage Linear Contrast Stretch [and] Piecewise Linear Contrast Stretch. 2, record 6, English, - linear%20contrast%20enhancement

The breadth of this histogram peak indicates the significant brightness variability in the scene.
