Explaining Activities as Consistent Groups of Events: A Bayesian Framework Using Attribute Multiset Grammars
<23>In 2007 (BMVC, not in RAE2008), the authors demonstrated that better explanations could be found for a particular activity by exploiting constraints between constituent events. This journal article is based on two substantial conference papers (IEEE-CVPR 2009, DOI:10.1109/CVPR.2009.5206636; BMVC’2009, DOI:10.5244/C.23.123) that develop this idea to: (i) handle many activities through specifying compositional structure and constraints using attribute multi-set grammars, (ii) evaluate potential solutions using Bayesian methods and (iii) optimise efficiently using MCMC. Based on this work (and [Hogg4]), Damen secured a Lectureship (in Bristol). The work is covered in a 2011 ACM Computing Surveys review on human activity analysis (DOI:10.1145/1922649.1922653).
