fixedering

Fixedering is a term that combines "fixed" and "dering" to describe a post-processing technique used in digital image and video processing to reduce or eliminate deringing artifacts. Deringing is the process of removing or reducing the appearance of ringing artifacts, which are visual distortions that appear as unwanted oscillations or ripples around edges or high-contrast areas in an image or video. These artifacts can occur due to various reasons, such as compression, resizing, or noise reduction processes.

In the context of fixedering, the term "fixed" implies that the deringing process has been applied to an image or video that already contains deringing artifacts. The goal of fixedering is to further refine and improve the quality of the image or video by reducing or eliminating these artifacts. This can be particularly useful in scenarios where the initial deringing process was not sufficient or when the image or video has undergone multiple processing steps that have introduced additional deringing artifacts.

Fixedering techniques can vary widely, depending on the specific requirements and constraints of the application. Some common approaches include the use of spatial filters, temporal filters, or a combination of both. Spatial filters operate on individual frames and can be designed to target specific types of deringing artifacts. Temporal filters, on the other hand, operate across multiple frames and can be effective in reducing deringing artifacts that persist over time. In some cases, machine learning algorithms can also be used to identify and remove deringing artifacts with a high degree of accuracy.

Overall, fixedering is an important technique in digital image and video processing, as it helps to improve the visual quality of images and videos by reducing or eliminating deringing artifacts. By applying fixedering techniques, it is possible to achieve smoother, more natural-looking images and videos that are free from unwanted oscillations and ripples.
