Welcome to my homepage !

I am a science enthusiast who enjoy discovering cultures and people all over the world. In my website you will find information about computer science such as image processing or machine learning. I also put some resources to the teachings I gave at University (C#, data mining, ...) and the scientific papers I published. You can also have a quick look to my hobbies. I like composing and playing music, traveling and coding.

About me

Since October 2014, I am research assistant professor at Osaka Prefecture University in the intelligent media processing group which is supervised by Professor Koichi Kise. I was involved in a national CREST project and working with researchers from Tohoku, Kyushu and KEIO Universities until 2016. We use devices such as cameras, eye-trackers, EoGs or smart glasses in order to get information from the reading activity. From 2017 we started a new notional CREST project with Todai and Kobe University about "experiential supplement". The aim is to creat new tool for sharing experiences for improving learning and education.

From 2012 to 2014, I was at the head of Research & Development at Gestform, a digitizing company of 340 people. I worked on many projects such as handwriting recognition, image classification, segmentation and recognition.

I am interested about signal analysis, image processing, machine learning, artificial intelligence and data mining. During my PhD.,I worked 3 years at LaBRI, the computer science laboratory of Bordeaux with Jean-Philippe Domenger (full professor) and Nicholas Journet (assistant professor).

In 2009, I worked 6 months at INRIA about designing multitouch interfaces for 3D interactions in Pascal Guitton team. He is now director of INRIA research. In 2008, I worked 4 months at Kumamoto laboratory. My internship was about chaos theory and its application for random number generation. My advisor was Akio Tsuneda. You will find in my resume more information about my education, my experiences, my skills... I also have some recommendation letters from Pascal Guitton, Jean-Philippe Domenger and Akio Tsuneda.


The list of my publications is available on Google Scholar or the dblp website. I am doing research about image analysis, processing and understanding; machine learning and artificial intelligence; eye tracking and physiological sensors.

Reading analysis with eye tracking systems

Since the end of 2014, I'm doing research about reading activity at Osaka Prefecture University. The main idea is to create a reading-life log to quantify and qualify the daily life reading habits. I extended the research of a tool for counting the number of read words named the Wordometer. We also proposed several educational applications such as estimating the English skill (TOEIC score), the Japanese skill or the confidence while answering multiple choice questions.

Mangas analysis

My research group in Osaka Prefecture University is also working on mangas analysis. Analyzing drawings is a very challenging task due to their variety. We proposed a new method to analyze the story telling based on genre classification with a deep learning approach. I also proposed a method to generate dynamic image visualization based on eye tracking, automatic animation of characters based on deep learning, and preliminary research about physiological signal analysis (heartbeat, sweating, skin temperature, etc.) while reading mangas.

Image analysis and machine learning

During my PhD at In Bordeaux university and Gestform digitizing company, I explored new techniques for image processing, analysis and comparison. I also studied machine learning, data mining and information retrieval. I used both image and text information for document image classification and indexation. I worked on many subjects such as : handwriting recognition based on Artificial Neural Network, document image classification based on bags of visual words, detection of check-box location and state, identity card robust and real-time retrieval, incremental learning with user interaction... I developed this techniques in C#, C++, R and applied them in industrial context.

Awards and grants

I was honored to win one best paper award at CIFED 2012.
In 2012, I got a young researcher grant to stay 3 weeks in the laboratory of my choice from LaBRI.
In 2013 I won the best student paper award at DRR 2013 for my works about semi-structured document image matching and recognition .
In 2015 I got Kakenhi young researcher grant (~4 millions JPY / ~30,000 EUR) to support my research about reading analysis and smart documents.
In 2017 I got the outstanding quality paper reviews award as reviewer of ICDAR 2017. I also got the outstanding service award for serving as local arrangement chair at ICDAR 2017.

I am teaching data mining at Osaka Prefecture University, more specifically about the following topics:

  • Link analysis and PageRank (Google) algorithm.
  • TrustRank and combating web spam.
  • Frequent itemset mining and association rules.
  • Clustering.
  • Recommender systems: content-based and collaborative filtering.
  • Recommender systems: Latent Factor Models, and the Netflix Challenge.

I also taught computer science at Bordeaux University. You can find here some of courses, but they are all in French.

  • XHTML and CSS : 5 lessons.
  • Image processing
    • lesson 1 : Introduction, Histograms and binary operation, exercises and images used for the exercise
    • lesson 2 : Contour detection, image transformation, exercises and images used for the exercises. Another exercise about geometrical transformation and morpho-math
    • lesson 3 : Pattern recognition and segmentation and image analysis. Exercises
    • lesson 4 : Image synthesis. OpenGL introduction
  • C2i : 6 lessons - linux, internet, word, excel, open office and powerpoint.
  • UML : lesson, exercise and quick reference card.
  • C# : exercises.


Music composition


I like to play guitar (acoustic and electric) and piano. I enjoy jazz, blues and rock music. I use essentialy a Guibson SG with a Marshall amplifier. I also have a Wah-Wah and a Big Muff footswitches. You can find my first compositions on Soundcloud and the music I like on my itunes profile.


For work or for leisure, I enjoy to visit many cities and to meet people all over the world such as in San Francisco, Kyoto, Beijing, Amsterdam, Barcelona, New York, Salzburg, Osaka, Venezia, London, Zaragosa...

Coding video games

When I was young I developed few video games with my teammates. Most of time we use C# and XNA or HTML5 and javascript. Here is some examples in HTML5:
