An Event Detection Framework Supported by a Smart Graphical User Interface

摘要: We develop a graphical user interface for defining events in framework detecting high-level surveillance from video stream, as the language used may be too complex an ordinary user. The is based on relational algebra extended by intervals, introducing operators whose temporal constraints are described using well-known Allen's interval relationships. captures intervals descriptive way, supporting providing missing parameters step-by-step manner. In background, system checks input consistency and automatically transforms it into expressions.
