Actions as Moving Points

January 2020

tl;dr: CenterNet for video object detection.

Overall impression

This extends CenterNet as Recurrent SSD extends SSD.

However it is still using box-based method to generate bbox and then link them to action tublets. This is more of a bottom up approach as compared to recurrent ssd.

Drawbacks and limitations: The main drawback is that it takes in K frames (K=7) frames at the same time. It is not suitable for fast online inference. It does support multiple object detection at the same time, same as CenterNet.
