In this study, human activity identification is approached as a record,
analyze and model from the video sequence as you observe the scene
in time methodology. The computational approach has two stages:
training and identification. During the training stage, specific human
activities are identified and characterised by employing modelling
of medium-term movement flow through streaklines. Each streaklines
is formed by multiple optical flow vectors that represent and
track locally the movement in the scene. A dictionary of activities
is recorded for a given scene during the training stage. During the
testing stage, the consistency of each observed activity with those
from the dictionary is verified using the Kullback- Leibler (KL) divergence.
Moving regions that are not present in the dictionary are
identified, triggering decisions such as those specific to anomalous
human activities.
