A Grid of Numbers
Captions available
The idea
A digital image reaches a machine as a grid of numbers — one brightness per cell, nothing else — and everything called seeing is built from arithmetic on the grid.
In practice
A modest photograph is a million cells, three numbers each for color: one case described by millions of features.
Where people slip
Between the grid and the label sits arithmetic — keep that sentence in view all block.
