Conclusion
This project has studied the application of knowledge about foveation in
the human visual system to video compression problems. We have confirmed
that single-user foveated video (as proposed in [2]) achieves up to
threefold compression gains over unfoveated video. We have also defined a
scenario for foveated video broadcast and suggested three alternative
schemes. Each scheme balances required receiver bandwidth with encoder
complexity. The main result is that joint foveation encoding achieves a
superior trade-off compared to naïve individual foveation.
