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 1, English, - linear%20contrast%20enhancement
