If you choose to participate, please imperatively register to the CFD for PIV workshop (to be held in Paris, November 19-20, 2020, and during which the results will be presented), and select 'Yes' for 'Intending to participate at DA- or LPT- challenge'. This is important as we will need to give soon further information to participants about upload of their processed data. For more informations on the workshop itself, please visit
