Compression: Description Principle
- 4K display: 3 x 10 bit/pixel x 40000 pixel x (3840 x 2160) x 48 frame/s = 5 x 10ˆ14.
- 4K compressed video: 44 -- 85 Mbps (4K)
- Optic Nerve: <1 Mbps (guinea pig), hence there is compression going on.
Estimation of information:
- How many spikes? Depends on neuron type.
- How many bits per spike? More spikes, less informative. (The rarer an event it is the more information it conveys).
- How much noise? By reproducibility.
