What is a Digital Image?

A digital image is a representation of a two-dimensional image as a finite set of digital values, called picture elements or pixels.
Pixel values typically represent gray levels, colours, heights, opacities etc
Remember digitization implies that a digital image is an approximation of a real scene.

What is Digital Image Processing?

Digital image processing focuses on two major tasks
Improvement of pictorial information for human interpretation
Processing of image data for storage, transmission and representation for autonomous machine perception
Some argument about where image processing ends and fields such as image analysis and computer vision start
