s are a type of black and white image that contains only two possible pixel values, typically 0 and 1. These images are often used in computer vision tasks and can be generated through techniques such as or . Thresholding involves selecting a particular pixel value as a threshold and classifying pixels below that threshold as black and pixels above it as white.

images, on the other hand, refer to images that use a single color channel but may not necessarily be grayscale. They can include images that utilize only a single hue such as sepia-toned photographs or various color filters.
