Outline

1. Image and Video Compression
   1. Image compression: JPEG
   2. Video compression: MPEG and H26x
2. Artifacts in Compression
   1. Spatial Artifacts: blocking and ringing
   2. Temporal Artifacts: mosquito and flickering
   3. Review on Methods for Quality Enhancement
3. Spatial Filtering for Quality Enhancement
   1. Blocking Artifacts Reduction: DCT-based low-pass filtering
   2. Ringing Artifacts Reduction: fuzzy filtering
4. Spatio-temporal Filtering for Quality Enhancement
   1. Motion Compensated Temporal Linear Filtering
   2. Adaptive Fuzzy Motion Compensated Spatio-temporal Filtering

Here is Quality Enhancement for Compressed Images and Videos
