How Asynchronous Events Encode Video

no code implementations9 Jun 2022 Karen Adam, Adam Scholefield, Martin Vetterli

Instead of recording video by capturing frames, event-based cameras have sensors that emit events when their inputs change, thus encoding information in the timing of events.

A Time Encoding approach to training Spiking Neural Networks

1 code implementation13 Oct 2021 Karen Adam

While Spiking Neural Networks (SNNs) have been gaining in popularity, it seems that the algorithms used to train them are not powerful enough to solve the same tasks as those tackled by classical Artificial Neural Networks (ANNs).

Asynchrony Increases Efficiency: Time Encoding of Videos and Low-Rank Signals

no code implementations29 Apr 2021 Karen Adam, Adam Scholefield, Martin Vetterli

Event-based sensing can present significant improvements in power efficiency when compared to traditional sampling, because (1) the output is a stream of events where the important information lies in the timing of the events, and (2) the sensor can easily be controlled to output information only when interesting activity occurs at the input.

Encoding and Decoding Mixed Bandlimited Signals using Spiking Integrate-and-Fire Neurons

1 code implementation21 Oct 2019 Karen Adam, Adam Scholefield, Martin Vetterli

We propose a setup to sample a set of bandlimited signals, by mixing them and sampling the result using different IF-TEMs.

Sampling and Reconstruction of Bandlimited Signals with Multi-Channel Time Encoding

2 code implementations12 Jul 2019 Karen Adam, Adam Scholefield, Martin Vetterli

In this paper, we show that, when using time encoding machines, reconstruction from multiple channels has a more intuitive solution, and does not require the knowledge of the shifts between machines.
