Post Reconstruction Filters in Video Compression

Certain tools in video encoders achieve maximum possible compression of raw video data. These compression techniques typically have perceivable artifacts on the reproduced video. The nature and extent of artifacts introduced purely depend on the combination of tools used in encoding the input video content.

Post reconstruction filters in video codec play a vital role in reducing such visual artifacts that can improve the video quality.

This paper provides an insight into various post-reconstruction filters in video codec standards along with the pros and cons of each technique.
