Why not considering event polarity #11

Closed robin-shaun closed 3 years ago

robin-shaun commented 3 years ago

Hello, I'm curious about why the time surface doesn't differentiate the event popularity. Is it useless but causing trouble to optimization?

Popularity -> polarity?

As we have cliaimed in our ECCV 2018 work, the introduction of polarity would not improve the mapping remarkably, but it may increase the computation burden by a factor of 2.

Thanks a lot!
