Principal investigator : Patricio ORIO and Thierry VIEVILLE
On going work : New functional models of non-linear local visual operators in order to encounter for dynamical and statistical pre processing of natural image sequences.
● Evaluation/Analysis of ICA methods
● Modeling motion direction selectivity observed in some retinal Ganglion Cells.
● Local and global image statistics operator
