Most PSS generate huge volume of raw data and they heavily rely on human operators to interpret and inference data in order to detect potential threats. Human Activity recognition is a challenging problem in due to complexity involved in low-level processing, data alignment from different sensor sources, and fusion of soft (e.g., human intelligence) and hard (physical sensors) data, and interpretation of fragmented, yet spatiotemporally correlated and associated information听 that enhance Situational Awareness (SA). Human activities may involve human-human interactions, human-object interactions, human-environment interactions or multi-human-object interactions or multi-human-multi-object interactions. Identifying human interactions as a group for high level activities have not been well addressed by previous researchers. High level activities may include operational activities involving Loading and unloading of objects, exchange of baggage, exchange of vehicles etc. Vehicles have been used as a primary source of transportation for pursuing many outdoor suspicious activities. Less attention has been devoted by previous researchers to discovery of human vehicle interactions via fusion of soft and hard sensor data.
The goal of this research work is to contribute to the advancement of Human Group Activity Interaction discovery and recognition in PSS for related DOD and DHS applications. In our research, image processing technique is used as the primary source of sensing modality.听For detecting and characterizing the events, and converting detected events to recognizable observations, a Casual Event State Inference (CESI) model is proposed. A Modified Sequential - HMM (MS-HMM) in conjunction with developed ontologies is used for predicting the group activities.听The MS-HMM model maps the sequential observations with the ontology library in building up its model. The end results as a semantic messages generated describing the human activities.
