AI City Challenge CVPR Virtual Workshop 2020

Due to the COVID-19 circumstance, this year’s AI City Challenge workshop is completely virtual same as the CVPR main conference. To better accommodate people attending the workshop online from all over the world, we try our best to find a shorter time window suitable for most potential workshop attendees and squeeze most interaction contents in and we will have the pre-recorded oral presentations playing back before the main interaction section.

We have the section time marked in multiple time zones and please use time zone map for assistance if needed.

Great thanks to all that make this workshop successful. Stay safe.
