Figure

Fig. 1. This coding/decoding architecture combines the perfect-LIF model (pink) with the neuro-inspired quantizer (blue) introduced in [7] where, d is the delay of the first spike, T is the observation duration and N the number of emitted spikes
Fig. 3. This figure illustrates the performance of the NQ as a non-uniform quanizer when the value of R is small and as a uniform quantizer when the value of R is arbitrarily large (set of parameters: θ = 5, C = 10 F and T = 100 ms.
Fig. 4. This coding/decoding architecture combines the perfect-LIF model (pink) with the conventional quantizer (green).
Fig. 6. This figure compares visually the performance of NQ and CQ when they are applied to the delays
