Welcome to my home page

I am currently a PhD student in Computer Science. I am working in the Image team of the GREYC CNRS UMR 6072 research laboratory, in Caen. My advisors are Mr. Abderrahim Elmoataz and Mr. Olivier Lézoray .

Research Interests

K Nearest Neighbrs Graph My research interests mainly concern discrete variational methods for the processing of functions defined on weighted graphs.
From these methods, I am investigating different application fields for the treatment of images, manifolds and unorganized data, such as
  • Mathematical Morphology for image, manifolds and unorganized data
  • Data simplification, clustering, semi-supervised learning
  • Image restoration, denoising, segmentation
