The images you see on internet pages and the photos you take with your mobile phone are examples of digital images.
It is possible to represent this kind of image using matrices. For example, the small image of Felix the Cat
can be represented by a 35 × 35 matrix whose elements are the numbers 0 and 1.
These numbers specify the color of each
[pixel].
the number 0 indicates black, and the number 1 indicates white.
Digital images using only two colors are called binary images or boolean images.
The (static) figure below shows an enlarged version of the image of Felix the Cat,
where each square represents a pixel. Its corresponding matrix is presented next.
