First of all, I am very grateful that you have made your database public, as it is very useful for my research.
In your paper and in the webpage information, you established that the annotation frame rate is 2 Hz, but in your youtube preview videos like this one it seems like you have a way obtain those annotations at a different frame rate.
I create this new topic in order to discover how do you perform this frame rate change. I could think of some kind of extrapolation by using a tracker or linear model, but the previews are really well annotated and it would be really helpful if you could explain me your method, since I am working in pedestrian intention prediction and with more information in the same time interval I could improve my results.
Thank you again for all your work.
