Compression Research
- scan image according to a space-filling curve
- variations of Z-transforms to increase locality
- store deltas (differences)
instead of new values
- store only 2-bit deltas (+1, 0, -1)
- play catch up
- periodically store actual (-2)
- store only 1-bit deltas (+1,-1)
- predict based on prior deltas
