Although local decisions are made, the output from a feature detection step does not need to be a binary image.

Punched card data was transferred to and from the core memory as binary images.

Apply a threshold to the 2D field to make a binary image containing:

As we can see, the first bit of a binary image clearly determines which complementary pair it belongs to.

These puzzles are often black and white, describing a binary image, but they can also be colored.

Structuring elements are particular cases of binary images, usually being small and simple.
