Phd student in human color vision and image processing. Am working on "Mise en évidence du démosaïçage couleur dans le système visuel humain." I work on designing experiements which can demonstrate demosaicing in the human visual system.

The idea is to design stimuli such as "minimum motion" which can be used to identify differences in the color perception of human subjects. Also am interested in developing demosaicing algorithms for digital cameras which are influenced by the HVS. I work on spatial-spectral optimisation of Color Filter Arrays for digital cameras so that we can capture and display better colors.
