PhD award of the Fondation Mines-Télécom

I have been awarded best PhD thesis from the Fondation Mines-Télécom!

Every year, a prize honors the best PhD thesis from the Futur & Ruptures program (co-funded by the Fondation Mines-Télécom and the Carnot institute Télécom & Société numérique).


After presenting the work I have done during my PhD at the Journée Futur & Ruptures (a day organized every year by the Fondation Mines-Télécom to present the work achieved during the PhD they funded), four of us were selected as finalists for the PhD award.

I then made a video (of 3 minutes, in french) summing up my work (long way to go before being a youtuber..!). The prizes were announced during the special event organized by the Fondation, which was held on the 27th of March at the BNP Parisbas headquarters in Paris.

The awards were given as follow:

1st prize: Sylvain Lobry – Markovian models for information extraction in SAR imagesTélécom ParisTech

2nd prize (tied):

El Mehdi Amhoud – Coding Techniques for Space Division Multiplexed Optical Fiber Systems – Télécom ParisTech

Yousra Bekhti – Source localization for functional brain imaging with M/EEG – Télécom ParisTech

Ivan Gorynin – Fast Filtering and Unsupervised Estimation in Switching Markov Models Télécom SudParis

It was a great evening, and I particularly enjoyed the interactions with the other recipients! Once again, I would like to thank the Fondation for this prize, as well as Loïc Denis, Florence Tupin, Roger Fjørtoft and Cyrielle Flosi for their advices on the video.

PhD defense – November 16th, 2017

On the 16th of November I defended my PhD at Télécom ParisTech. The title is:

Markovian models for SAR images:

Application to water detection in SWOT satellite images and multi-temporal analysis of urban areas

In front of the jury:

You can find more information (including manuscript, slides, animations…) on the dedicated page.

I wanted to thank everyone who made this day feel really special, starting with the member of the jury. Thanks to their challenging questions, the defense was a moment that I enjoyed!

And I would like to thank my colleagues, friends and family who came and organized the traditional cocktail. It was great seeing all of you!

I just came back from IGARSS 17 which took place at Fort Worth, Texas, USA. I did two oral presentations on algorithms dedicated to Water detection in SWOT images:

  • The first one is dedicated to the detection of large water bodies and uses two Markov Random Fields iteratively: the first one do the actual classification, while the second ones estimates the parameters of the class distributions.
  • The other algorithm detects thin water surfaces (such as rivers). It combines a pixel-based detector (which detects parts of the river network) and a higher-level step connecting detected segments.

More information can be found in the proceedings posted in the publication page.

Demo – Water detection on SWOT images

Last week, I participated at the “Journée Futur & Ruptures” organized by the fondation which finances half of my PhD (the other half being financed by the CNES).

This year, I was asked to prepare a demo. I did some kind of an interactive class that leads to the model I have been working on in the past months. The goal is to detect water in SWOT images.

You can find it here. Do not hesitate to contact me if you have remarks or if you find a bug.

New poster

Last october, I participated to the “Journées CNES Jeunes Chercheurs 2016” (JC2), where I had the chance to give a short talk and present a poster about the work I have done so far at my PhD. It was a great opportunity for me to present my work to talented scientists from very different fields!
As this poster sum up what I have been up to, I thought it would be nice to put it here.

Unfortunately, it is in French… If you only speak english (or want more details!), feel free to take a look at the updated publiactions page!
