General Interaction Recognition
Detecting key actions like kicking and punching as part of general Interaction detection was the initial step towards violent action recognition. Many methods were proposed for this purpose which includes Background subtraction or Human detection, Feature extraction and Classification. [4] address the problem of detecting human violence in video, such as fist fighting, kicking, hitting with objects. To detect violence this method rely on motion trajectory information and on orientation information of a person’s limbs. It defines an
Acceleration Measure Vector (AMV) composed of direction and magnitude of motion and defines jerk to be the temporal derivative of AMV.
Initially Background Subtraction is done to acquire the silhouettes of moving
