Temporal Action Detection with Structured Segment Networks

https://arxiv.org/pdf/1704.06228.pdf

SSN Structured Segment Network

• Tress-Stage Structured

  starting -- course -- ending

• Structured Temporal Pyramid Pooling

  course : two-level ( split number )

  starting & ending : one-level

• Two classifiers

  activity

  completeness

• Location Regression and Multi-Task Loss

  refine the boundary

TAG Temporal Actionness Grouping

• Actionness probabilities -- binary classifier

• Complemented actionness -- watershed algorithnm
