postfiltered
Postfiltered refers to data or signals that have undergone an additional filtering stage after an initial processing step. In signal processing and communications, post-filtering is applied to reduce residual noise, suppress artifacts introduced by compression or transmission, or to shape the frequency content of a signal once the primary algorithm has completed.
Common domains for post-filtering include audio processing, image and video processing, and communication systems. In audio
Techniques used for post-filtering vary with the domain and goal. They include adaptive filtering, Wiener filtering,
Design considerations for post-filtering emphasize the trade-offs between improved signal quality and computational load, processing delay,
Postfiltered data is thus a flexible concept describing any result that has been refined by a follow-up
