\section{Introduction}
\label{sec:introduction}

This is the template for abstract submissions to the research school and the four conferences of the 2021 CIRM thematic month on ``Mathematics for Signals, Images and Structured Data''. 



\section{Abstract submission}
\label{sec:first-section}

The abstract must be at maximum one page long, with an additional second page for tables, figures and references only. Please submit your abstract on the program website \href{https://msisd2021.sciencesconf.org/}{https://msisd2021.sciencesconf.org/} in the \emph{pdf} format no later than \emph{October, 18th 2020} (no deadline extension will be possible).


\section{Final submission}
\label{sec:second-section}

The confirmation of accepted extended abstracts will be on November, 2nd 2020. The final papers will have to be submitted on the website, \emph{including all the source files (tex, figures, etc)} in a zip archive by \emph{December, 31st 2020}. This will enable to compile all abstracts together and publish them in open access proceedings on arXiv without any copyright restrictions to facilitate publication of further details elsewhere.
