Boolean Operations
The basic set of Boolean operators are AND (pixels that are on in both images), OR (pixels that are on in either image), and Exclusive-OR (pixels that are on in one or the other image but not both). Combined with NOT (the logical inverse) this allows selecting various sets of pixels. This interactive tutorial illustrates the basic Boolean functions used to combine binary images.
The tutorial initializes with a specimen image appearing in the left-hand window entitled Specimen Image. The Display Image buttons allow selection of one of two binary images used as inputs for the various combinations. The Boolean Combination pull-down menu allows selection of various combinations of these two images in order to demonstrate the meaning of AND, OR, Exclusive-OR, and NOT.
