"Posterisation" Meaning
Posterization, also known as posterization artifact, is a term used in image processing and digital photography to describe the appearance of banding or quantization artifacts that occur in digital images, particularly in digital photographs and digital paintings.
It is caused when an image is captured and stored in a lossy digital format, such as JPEG, which uses a technique called discrete cosine transform to compress the image data. This transformation results in the image being quantized, or split into a series of discrete values, which can lead to the appearance of banding or posterization.
Posterization can occur when there are large gradients in the image, such as in transitional areas between different colors or in areas with high brightness or contrast. It can also occur when the image is enlarged or displayed at a low resolution, causing the quantization artifacts to become more noticeable.
There are three ways to get rid of a posterization of the image:
- Increase the number of bits per pixel
- Increase the number of color levels in the image
- Increase the grayscale levels in the image.

This can refer to the process of preserving a moment in time or freezing a scene in place.
Posterization
Posterization is a technique used in digital image processing and photography to create a divided image that resembles a poster. It involves dividing an image into distinct levels of color, resulting in a visual effect similar to an airbrush or hand-tinted artwork from photographs in the early 20th century.<br><br>In the process, the image is digitally split into two or more levels of intensity or brightness, then reintroduced at its full intensity, causing loss of intermediate color steps or "posterized" edges. The overall effect is dramatic, with abrupt transitions between regions. This can add an aesthetic style to the image.
