A process of creating a black-and-white image out of a grayscale image consisting of setting exactly those pixels to white whose value is above a given threshold, setting the other pixels to black
When converting a pixel from grayscale to black and white, the threshold is the gray value above which will be considered white, and below or equal to will be considered black
A technique used primarily with surface rendering, in which a density value of the interface between two materials in the dataset is selected so that the interface surface can be identified for rendering [KAU91]
A point operation that maps all the pixel values of an image that fall within a given range to one of a set of per-band constants
Scene segmentation process based on converting a gray-scale image into a binary image by reassigning pixel gray levels to only two values Regions of the binary image are separated based on whether pixel values in the gray scale image were above or below a chosen intensity level
The boundary in spectral space beyond which a data point (pixel) has a sufficiently low probability of being included in a given class and, therefore, is purposely excluded from that class
