Boundary Discretization and Reliable Classification Network for Temporal Action Detection. (arXiv:2310.06403v2 [cs.CV] UPDATED)
cs.CV updates on arXiv.org arxiv.org
Temporal action detection aims to recognize the action category and determine
the starting and ending time of each action instance in untrimmed videos. The
mixed methods have achieved remarkable performance by simply merging
anchor-based and anchor-free approaches. However, there are still two crucial
issues in the mixed framework: (1) Brute-force merging and handcrafted anchors
design affect the performance and practical application of the mixed methods.
(2) A large number of false positives in action category predictions further
impact the detection …
