New adaptive filters as perceptual preprocessing for rate-quality performance optimization of video coding

作者：

Highlights：

• Perceptual pre-filtering for rate-quality optimization of video codecs.

• High bit rate saving for same subjective quality demonstrated with an H.264/AVC and an HEVC codec.

• Perceptually -guided filters offering a good trade-off between noise removal, blurring and complexity.
