It is controversial whether temporal spike coding or rate coding is dominant in the information processing of the brain. We show by a two-layered neural network model with noise that, when noise is small, cortical neurons fire synchronously and intervals of synchronous firing robustly encode the ...
Information may either be represented as the average number of spikes per unit time (rate coding)1,2 or by their precise timing (temporal coding)3. The nervous system may also utilize a combination of both strategies, suggesting a continuum between these two extreme coding schemes4. Indeed, ...

Central sensory processing uses also rate coding, and motor outputs appear to be primarily encoded by rate. I propose here a simple, efficient structure, converting temporal coding to rate coding by neuronal phase-locked loops (PLL). The simplest form of a PLL includes a phase detector (that ...
The coding fraction equals 0.83 in this example. B. Signal-to-noise ratio computed as in Eq. (23.4).Adapted from Gabbiani and Metzner (1999). The optimal reconstruction filter can be computed analytically under the following two assumptions. First, we assume that the firing rate and the ...
The optimization problem is complicated even further because the rate-distortion costs are not generally independent for all coding units, for example, because of the spatial and/or temporal dependencies introduced through intra- and inter-prediction. This means that the Lagrangian optimization of Eq....
Recent Spiking Neural Networks (SNNs) works focus on an image classification task, therefore various coding techniques have been proposed to convert an image into temporal binary spikes. Among them, rate coding and direct coding are regarded as prospective candidates for building a practical SNN ...
Video streams are generated using a combination of Multiple Bit Rate (MBR) encoding and Scalable Video Coding (SVC). Capabilities and requests of the clients are used in determining
A technique to reduce blocking and ringing artifacts in low bit-rate block-based video coding is applied to each reconstructed frame output from the decoder. For each pixel block of a reconstructed frame, its DC value and DC values of the surrounding eight neighbor blocks are exploited to predi...
