When we take a digital image, it is essentially a grid of tiny coloured dots called pixels. A pixel is the smallest unit of a
digital image or graphic that can be displayed and manipulated on a digital display device. Each pixel represents a small
part of the image and contains information about its colour and intensity. The resolution of an image is expressed as
the total number of pixels along its width and height. For example, an image with a resolution of 1920x1080 pixels have
1920 pixels horizontally and 1080 pixels vertically. Higher-resolution images have more pixels, providing more detail.
AI helps make sense of these images by converting them into numbers. Computers break down the image into a series
of numbers representing the colour and intensity of each pixel. This numerical representation allows AI algorithms
to process the image mathematically and extract meaningful information from it. For instance, AI algorithms might
learn to recognise patterns in these numbers that correspond to specific objects, like cars or faces. By analysing large
amounts of labelled image data, AI systems can “learn” to identify objects accurately.

For example, self-driving cars use computer vision to navigate roads safely. They analyse images and videos from
cameras mounted on the car to recognise traffic signs, detect pedestrians, and identify other vehicles. This allows the
car to make real-time decisions, such as stopping at a red light or swerving to avoid an obstacle.
