2006
EURASIP Journal on Advances in Signal Processing
Preserved Fulltext
We present a mixed-state space approach for modeling and segmenting human activities. ...
The discrete-valued component of the mixed state represents higher-level behavior while the continuous state models the dynamics within behavioral segments. ...
Mixed-state models Mixed-state models have been used for several applications including activity modeling, air traffic management, smart highway system, and so forth (see [17] [18] [19] [20] ). ...
