Clauselets: Leveraging Temporally Related Actions for Video Event Analysis

Hyungtae Lee, Vlad I. Morariu, Larry S. Davis
2015 2015 IEEE Winter Conference on Applications of Computer Vision  
We propose clauselets, sets of concurrent actions and their temporal relationships, and explore their application to video event analysis. We train clauselets in two stages.  ...  We initially train first level clauselet detectors that find a limited set of actions in particular qualitative temporal configurations based on Allen's interval relations.  ...  We note that 2 nd level clauselets provide the more descriptive analysis with comparable detection performance, since multiple actions are related to each other temporally.  ...
