Complex human activities occurring in videos can be defined in terms of temporal configurations of primitive actions. Prior work typically hand-picks the primitives, their total...
A prototype Basic LOTOS interpreter, augmented for modelling real-time systems, is described. Primitive actions are treated as time-consuming, with separate start and end points, ...
We present a new method for segmenting actions into primitives and classifying them into a hierarchy of action classes. Our scheme learns action classes in an unsupervised manner ...
