What is the Digitization definition in digital image processing?

Digitization in digital image processing refers to the process of converting an analog image into a digital format that can be processed by a computer. This involves two main steps: sampling, where the continuous signal is measured at discrete intervals, and quantization, where these sampled values are assigned a finite number of levels or values. The result is a grid of pixels, each representing a specific intensity or color value, allowing for efficient storage, manipulation, and analysis of the image in digital form.
