Binary image – an image of the multiphase type whose pixels have only two possible intensity values: 0 and 1. Binary images are used in logic, morphology and measurement functions They are usually produced from grayscale or true-color images by performing segmentation or thresholding in order to separate objects of interest from the background. Pixels whose values are equal to 1 correspond to the foreground objects, while pixels with zero values represent the background. By default ImageWarp displays the foreground in red color and background in black.
