Noise Reduction Preprocessing for MPEG-2 Encoding

In the real world, all video content contains some noise. Even modern facilities equipped with the latest digital production equipment will inevitably import noisy content. Archival material, film, and news feeds contain high levels of noise. Noise reduction (NR) and filtering can substantially improve the image quality received by the viewer if the appropriate techniques are gracefully applied to remove the noise prior to compression. Selectively removing noise is a challenge because it shares the same bandwidth as valuable picture detail. An ideal noise reduction process will allow suppression of all types of noise while preserving clean video content. An advanced noise reduction system will use sophisticated techniques that offer powerful abilities to remove noise without introducing side effects such as motion blur or ghosting.
