Titre de la thèse / Title of the thesis:
Information encoding and perception through neural systems

Laboratoire d’accueil / Host Laboratory : ImViA

Spécialité du doctorat préparé : Instrumentation et informatique de
l’image

Mots-clefs / Keywords : stochastic process – neuronal model – signal
analysis

Descriptif détaillé de la thèse / Job description

Over the last years, the way neurons encode information has been the
subject of various studies and still attracts the interest of researchers
owing to the potential bio-inspired applications. Various fields are
concerned such as perception of sensorial stimuli, information processing,
bio-inspired circuits and of course artificial intelligence.

This project falls within this interdisciplinary context since we propose
to study how deterministic or stochastic perturbations may interfere in the
process of information encoding, information detection and information
perception through models of neurons which would be acting on their own or
as a network.

For instance, the case of one-dimensional stimuli will be considered in a
parallel neural network where we propose to analyze how noisy perturbations
can enhance the information encoding via the supra-stochastic resonance
phenomenon. Depending on the applicant’s skills, an experimental analysis
will be also carried out by exciting an electrical neurons circuit via
various appropriate types of excitations in order to validate the
theoretical and numerical findings.

A complementary part of this project will consist in taking into account
the two-dimensional stimuli, that are images. The impact of specific
perturbations on the perceived image quality will be investigated by
considering both ordered or random perturbations as they can take place in
the image dithering process.
